Ítem Modelado Tridimensional y Análisis Funcional de una Cabria para la extracción del mineral(DYNA INGENIERÍA E INDUSTRIA, 2013-07-27) Rojas-Sola, José Ignacio; Montalvo-Gil, Juan Manuel; Castro-García, MiguelEn el presente artículo se analiza en detalle un ejemplo del patrimonio industrial minero del antiguo distrito minero de Linares-La Carolina (Jaén, España), como es una cabria de mampostería con su castillete metálico, utilizada en la extracción del mineral de plomo, concretamente de galena o sulfuro de plomo. En particular, se ha realizado el modelado tridimensional con ayuda de software paramétrico gracias a técnicas empíricas de cada uno de los elementos que componen el conjunto. Asimismo, una vez obtenido el modelo 3D, se ha realizado un análisis funcional mediante técnicas de Ingeniería Asistida por Ordenador, basadas en el análisis tensional y el análisis de desplazamientos, comprobando que las mayores concentraciones de tensiones se producen en la parte media e inferior de los muros, que los mayores valores de tensión se producen en los alrededores de los huecos de los muros, y que la mayor concentración de desplazamientos de la cabria de mampostería se encuentran en los muros en la parte media y superior, y del castillete en las correas de la cubierta.Ítem Methodology for intelligent plastic injection point location based on geometric algorithms and discrete topologies for virtual digital twin environments(FEDERACION ASOCIACIONES INGENIEROS INDUSTRIALES ESPANAALAMEDA DE MAZARREDO, BILBAO 69-48009, SPAIN, 2014-01) Mercado-Colmenero, Jorge Manuel; Torres-Alba, Abelardo; Martin-Doñate, CristinaImplementing intelligent design models can revolutionize the use of digital twins, which are crucial in product design by incorporating intelligent algorithms. This perspective is especially important for the design of injection-molded plastic parts, a complex process that often requires expert knowledge and costly simulation software not available to all companies. This article presents an innovative methodology for locating injection points in injection-molded parts using intelligent models with geometric algorithms for discrete topologies. The first algorithm calculates the center of mass of the discrete model based on the center of mass of each triangular facet in the system, ensuring uniform molten plastic distribution during mold cavity filling. Two sub-algorithms intelligently evaluate the geometry and optimal injection point location. The first sub-algorithm generates a geometric matrix based on a two-dimensional nodal quadrature adapted to the part's bounding box. The second sub-algorithm projects the nodal matrix and associated circular areas orthogonally on the part's surface along the demolding direction. The optimal injection point location is determined by minimizing the distance to the center of mass from the first algorithm's result. This novel methodology has been validated through rheological simulations in six case studies with complex geometries. The results demonstrate uniform and homogeneous molten plastic distribution with minimal pressure loss during the filling phase. Importantly, this methodology does not require expert intervention, reducing time and costs associated with manual injection mold feed system design. It is also adaptable to various design environments and virtual twin systems, not tied to specific CAD software. The validated results surpass the state of the art, offering an agile alternative for digital twin applications in new product design environments, reducing dependence on experts, facilitating designer training, and ultimately cutting costsÍtem Electrical consequences of large-scale replacement of metal halide by LED luminaires(SAGE Publications LTD, 2016-05-04) Hermoso Orzáez, Manuel Jesús; Rojas Sola, José Ignacio; Gago Calderón, AlfonsoThe recent trend for large-scale replacement of luminaires using discharge light sources with LED luminaires without any significant adjustments to the electrical installation has generated controversy. This study examines the main electrical measures in a large outdoor lighting installation before and after the replacement of a large number of metal halide floodlights with LED luminaires. The electrical parameters of both technologies are discussed in detail and compared, with special attention given to the odd-numbered harmonics of voltage and current, the generated wave deformation, currents in the neutral conductor, the wattless reactive volt amps and the peak inrush currents. At cold start-up, the LED luminaires generate large power-on currents, much larger than those generated by the metal halide lamps, despite requiring 36% less real installed power. This is a basic problem to be solved when planning a public lighting renovation with LED luminaires as the rest of electrical parameters are reduced. To address this problem, it is proposed to energise the luminaires using magneto-thermal protection circuits with slow trip curves that will tolerate the large short-term inrush currents.Ítem A Design Alternative to Improve the Interconnection Capability of New Distributed-Generation Installations into Existing Griddle(Multidisciplinary Digital Publishing Institute, 2016-05-27) Agüero, José; López-Martínez, Javier; Rojas-Sola, José Ignacio; Callejón, Ángel JesúsMost distributed-generation facilities are performed on pre-built distribution grids. The design conditions of these existing grids may limit the ability of new users to get a connection due to technical and/or cost constraints. This work proposes a simple solution, adjusted to the relevant regulations and embodied in a radial distribution grid of Spanish low voltage, to improve the interconnection of distributed generation, usually grid connected photovoltaic systems. The proposed solution, based on increasing the section of the neutral line, achieves a capacity of increasing the length of the supply grid by more than 20%.Ítem An interactive photogrammetric method for assessing deer antler quality using a parametric Computer-Aided Design system (Interactive Photogrammetric Measure Method)(ELSEVIER, 2016-07-19) Rubio-Paramio, Miguel Ángel; Montalvo-Gil, Juan Manuel; Ramírez-Garrido, José Alberto; Martínez-Salmerón, Débora; Azorit, ConcepciónIn the area of deer antler evaluation for trophy homologation, as well as in the obtaining of biometric databases for later analysis in the field of Geometric Morphometrics, different linear biometric tools have traditionally been used. In this study we used two sets of antlers from 29 Iberian red deer (Cervus elaphus hispanicus) to develop and establish a new photogrammetric technique which creates the 3D model of the antler using a parametric 3D Computer-Aided Design (CAD). This simple and reliable method for deer hunting trophy homologation was compared with the other two more extensively used methods of antler measurement, the traditional measuring tape and the Articulated Arm Coordinate Measuring Machine (AACMM or CMA). The advantage of this innovative photogrammetric method is the use of only two photographs to obtain both the 3D model and the dimensions required for antler evaluation. A procedure was performed to compare lengths and antler evaluation as hunting trophy. The three methods showed similar reliability, although the photogrammetric process using the 3D CAD system was much faster and more functional than both the traditional measuring tape and Articulated Arm methods. Since this method only requires two photographs per individual, it makes possible the study of a high percentage of antlers in the field. This new photogrammetric method has been successfully used in the biometrics area, but it could become a more extensively used method in this and other fields because of its ease of operation, speed and accuracy of data collection.Ítem A new hybrid method for demoldability analysis of discrete geometries(Elsevier, 2016-07-27) Mercado-Colmenero, Jorge Manuel; Rubio-Paramio, Miguel Ángel; Pérez-García, Jesús MaríaIn this paper, a new method for demoldability automatic analysis of parts to be manufactured in plastic injection is presented. The algorithm analysis is based on the geometry of the plastic part, which is discretized by a triangular mesh, posing a hybrid discrete demoldability analysis of both the mesh nodes and facets. A first preprocessing phase classifies mesh nodes according to their vertical dimension, assigning each node a plane perpendicular to the given parting direction. By selective projection of facets, closed contours which serve as the basis for calculating the demoldability of the nodes are created. The facets are then cataloged according to demoldability nodes that comprise demoldable, non-demoldable and semi-demoldable facets. Those facets listed as semi- demoldable are fragmented into demoldable and non-demoldable polygonal regions, causing a redefinition of the original mesh as a new virtual geometry. Finally, non-demoldable areas are studied by redirecting the mesh in the direction of the sliding side, and again applying the processing algorithm and cataloging nodes and facets. Resoluble areas of the piece through mobile devices in the mold are obtained. The hybrid analysis model (nodes and facets) takes advantage of working with a discrete model of the plastic part (nodes), supplemented by creating a new virtual geometry (new nodes and facets) that complements the original mesh, providing the designer not only with information about the geometry of the plastic piece but also information on their manufacture, exactly like a CAE tool. The geometry of the part is stored in arrays with information about their manufacture for use in downstream applications.Ítem Evolution of the cost and economic profitability of grid-connected PV investments in Spain: Long-term review according to the different regulatory frameworks approved(Elsevier, 2016-12) López-Talavera, Diego; Muñoz-Cerón, Emilio; Ferrer-Rodríguez, J.P.; Nofuentes, GustavoSpain has shifted from a predominant position in the worldwide market according to the accumulated PV power installed, to an irrelevant level where it is even no longer present at the PV market survey; but not always this has been the situation. The Spanish Government have promoted renewable energy policies which have turned very rapidly from a promising scenario, especially in the 2004–2008 period, into an unstable situation not only for future investors in this technology, but also for current owners that have been witnesses of a decrease in their profitability expectations. Furthermore, although the retroactive measures that have been applied to the owners of these PV plants could be, paraphrasing the Government words, “reasonable profitable”, the problem arises when they may be unable to afford the annual liquid assets of the funding mechanism chosen for their PV investments. Therefore, in a scenario where in the last decade more than 12 laws and Royal Decrees have been promulgated in Spain, it is interesting to review the effects in the profitability and cost parameters that this legislation has had on the PV market, on the owners and also on prospective investors. In this paper a complete economic profitability and cost analysis based on the NPV, IRR and LCOE has been undertaken for the case of Spain since 1998, correlating it to the evolution of the legislative framework applicable to the photovoltaic technology.Ítem Comparison of two PV array models for the simulation of PV systems using five different algorithms for the parameters identification(Elsevier, 2016-12) Kichou, Sofiane; Silvestre, Santiago; Guglielminotti, Letizia; Mora-López, Llanos; Muñoz-Cerón, EmilioSimulation is of primal importance in the prediction of the produced power and automatic fault detection in PV grid-connected systems (PVGCS). The accuracy of simulation results depends on the models used for main components of the PV system, especially for the PV module. The present paper compares two PV array models, the five-parameter model (5PM) and the Sandia Array Performance Model (SAPM). Five different algorithms are used for estimating the unknown parameters of both PV models in order to see how they affect the accuracy of simulations in reproducing the outdoor behavior of three PVGCS. The arrays of the PVGCS are of three different PV module technologies: Crystalline silicon (c-Si), amorphous silicon (a-Si:H) and micromorph silicon (a-Si:H/μc-Si:H). The accuracy of PV module models based on the five algorithms is evaluated by means of the Route Mean Square Error (RMSE) and the Normalized Mean Absolute Error (NMAE), calculated for different weather conditions (clear sky, semi-cloudy and cloudy days). For both models considered in this study, the best accuracy is obtained from simulations using the estimated values of unknown parameters delivered by the ABC algorithm. Where, the maximum error values of RMSE and NMAE stay below 6.61% and 2.66% respectively.Ítem Agustin de Betancourt’s Wind Machine for Draining Marshy Ground: Approach to Its Geometric Modeling with Autodesk Inventor Professional(Multidisciplinary Digital Publishing Institute, 2016-12-26) Rojas Sola, José Ignacio; De la Morena de la Fuente, EduardoThe present study shows the process followed in making the three-dimensional model and geometric documentation of a historical invention of the renowned Spanish engineer Agustin de Betancourt y Molina, which forms part of his rich legacy. Specifically, this was a wind machine for draining marshy ground, designed in 1789. The present research relies on the computer-aided design (CAD) techniques using Autodesk Inventor Professional software, based on the scant information provided by the only two drawings of the machine, making it necessary to propose a number of dimensional and geometric hypotheses as well as a series of movement restrictions (degrees of freedom), to arrive at a consistent design. The results offer a functional design for this historic invention.Ítem Spectral characterization of the solar resource of a sunny inland site for flat plate and concentrating PV systems(Elsevier, 2017-02) García, R.; Torres-Ramírez, Miguel; Muñoz-Cerón, Emilio; de la Casa, Juan; Aguilera-Tejero, JorgeThe spectrum is not frequently used when rating any PV technology. Moreover, in those energy predictions where it is considered, normally they are based on simulated models. The objective of this work is the spectral characterization of the solar resource based on real measurements as their availability in the scientific community is scarce. For this characterization the Average Photon Energy is used, which has been obtained from an experimental campaign carried out in Jaén (Spain) based on three different configurations: Direct Normal spectrum (DNI tracker), Global spectrum on a tracking system (Gl tracker) and Global spectrum on a fixed surface (Gl fixed). The results show that the annual irradiance weighted average value of APE results in 1.80 eV for DNI tracker, 1.85 eV for Gl tracker and 1.86 eV for Gl fixed, showing a red spectral shift for the DNI measurements. A Red-rich spectrum prevails, so this location is especially suitable for single junction materials with a large absorption band such as CIGS and c-Si. Besides, GI tracker spectra are slightly redder than GI fixed ones, consequently, if c-Si modules are used, spectral gains with 2-axis tracking will be higher than those achieved with a fixed arrangement of such modules.Ítem Power Quality and Energy Efficiency in the Pre-Evaluation of an Outdoor Lighting Renewal with Light-Emitting Diode Technology: Experimental Study and Amortization Analysis(Multidisciplinary Digital Publishing Institute, 2017-06-22) Hermoso Orzáez, Manuel Jesús; Gago Calderón, Alfonso; Rojas Sola, José IgnacioIn this work, a practical methodology is proposed to analyze, before undertaking a large investment, an outdoor lighting installation renewal with light-emitting diode (LED) luminaires. The main problems found in many of the luminaires tested are associated with inrush peak currents in cold start (which may cause ignition problems with random shutdowns), the harmonic distortions caused by their AC/DC associated electronic nature driver, and their working and efficiency dependency on the ambient temperature. All these issues have been tested in the context of a large metal halide (MH) to LED luminaires lighting point renewal where six commercial LED projectors have been analyzed with the above considerations. This research has isolated a single-phase circuit powered with constant stabilized 230 VAC voltage source in a real public lighting installation. All of them have been sequentially installed and their main electrical and power-quality parameters measured and recorded. The results indicate that each luminaire option will influence the expected long-term reliability (>50.000 h or more as expressed by the U.S. Department of Energy) of the lighting installation (in the case poor power quality is generated on the grid). The economic analysis made to estimate the profitability of the investment may be severely affected by the difference between the declared and the real consumption values in which they perform in our specific installation.Ítem Cradle-to-cradle approach in the life cycle of silicon solar photovoltaic panels(Elsevier, 2017-12) Contreras-Lisperguer, Rubén; Muñoz-Cerón, Emilio; Aguilera-Tejero, Jorge; de la Casa, JuanThe penetration rates of solar photovoltaic (PV) technology have growth exponentially and are expected to continue growing. Consequently, in the medium term, the volume of PV panels to be decommissioned will also increase, thus creating a massive amount of waste with resulting negative environmental implications. Among the methodologies that tackle the challenges for reducing the use of non-renewable abiotic resources and the level of waste, the novel cradle-to-cradle (C2C) manufacturing approach states that we can maintain our current levels of economic growth without damaging the environment and promoting a shift in the concept of re-cycling. While the possibility of applying C2C principles within a closed-loop material cycle (CLMC) looks promising, it still requires further research and improvement, particularly to support robust business decisions and policy development. This paper first presents the main challenges and opportunities for C2C implementation for silicon-based solar PV modules, given the complexity of creating and maintaining a true CLMC system. It then calls for urgent development of a credible scientific framework for system modelling, based on thermodynamics and mathematics, in order to truly move from re-cycling to up-cycling. As an initial step, a conceptual model and a suitable time-space scale for the required C2C-CLMC system is proposed.Ítem A numerical and experimental study of a new Savonius wind rotor adaptation based on product design requirements(Elsevier, 2018-01-09) Mercado-Colmenero, Jorge Manuel; Rubio-Paramio, Miguel Ángel; Guerrero-Villar, Francisca; Martín-Doñate, CristinaThis paper presents the numerical-experimental study carried out on a new rotor adapted from a Savonius rotor. Aesthetic, ergonomic and functional requirements have been incorporated into it in order to be part of sustainable consumer products. The new rotor consists of a parametric model adaptable to the dimensions and geometry of the products which it will be part of. A set of translation, symmetry, rotation and scaling operations have been applied to the bucket sections of the Savonius rotor by means of transforming the initial cylindrical buckets into topological surfaces with an organic shape. The new modified Savonius rotor and the conventional Savonius with the same Aspect Ratio have been tested in an open jet wind tunnel in order to verify the influence level of product design parameters on rotor performance, in terms of power coefficient, torque coefficient and mechanical power generated. Experimental tests have been carried out for Reynolds values in the range of [3,430·104 and 1,419·105]. A numerical analysis using an incompressible unsteady Reynolds average Navier Stockes model has been validated by means of the experimental results. Experimental and numerical results coincide with a 3.5% error. The behavior of the turbine has been analyzed by varying the angle of rotation for the sections of its buckets. Using a rotation angle of 45 ° the power coefficient values improve by 32% compared to the values obtained using an angle of 0 °. The rotor has been dimensioned for its application in a patented consumer product of small dimensions and requirements of lateral accessibility to its interior. Under these limited conditions the rotor meets the small-scale energy requirements of the product. The new rotor is designed as an aid to the energy consumption of the product in which it is incorporated, maintaining the advantages of a conventional Savonius rotor as self-starting, easy manufacture and maintenance, obtaining at the same time a product that sells better, is more able to integrate into its environment and is customizable for the consumer.Ítem Geometric Modeling of the Machine for Cutting Cane and Other Aquatic Plants in Navigable Waterways by Agustín de Betancourt y Molina(Multidisciplinary Digital Publishing Institute, 2018-02-11) Rojas Sola, José Ignacio; De la Morena de la Fuente, EduardoThis article presents the steps followed to obtain a three-dimensional model of one of the most recognized historical inventions of Agustín de Betancourt y Molina from the scant documentation found about it. Specifically, this was a machine for cutting cane and other aquatic plants in navigable waterways, presented in London in 1795. The study is based on computer-aided design (CAD) techniques using Autodesk Inventor Professional, from the information provided by the only two sheets that exist from the machine, one with specifications in English and the other in French, both very similar. In order to obtain a functional result on which to carry out further studies, it has been necessary to make some geometrical hypotheses on the models, aimed to find the correct dimension of each element. In addition, it has also been necessary to define the relationship of each element with those that set up its environment, defining movement restrictions, so that the final model, behaves as real as possible.Ítem VIRTUAL REBUILDING OF PUENTE DE TABLAS AN, OLIVE OIL FACTORY AT PRIEGO DE CORDOBA (SPAIN)(UNIV POLITECNICA VALENCIA, EDITORIAL UPV, 2018-03-26) Lopez-Quintero, Javier Luís; García-Molina, Diego FranciscoLa emblemática almazara Puente de Tablas situada en Priego de Córdoba se ha perdido con el paso de los años debido a las diferentes obras de urbanización y reconstrucción realizadas en la zona. Este artículo resume tanto el estudio de la ubicación como de la reconstrucción virtual 3D de todos sus componentes constructivos y funcionales, valiéndose del descubrimiento del plano inédito conservado desde 1802 –época en la que la almazara aún estaba activa– en el Archivo de la Real Chancillería de Granada. También se hace uso de: (a) los escasos restos que aún perduran, (b) los estudios arqueológicos realizados en esta ubicación, (c) construcciones similares en comarcas cercanas, así como de (d) las últimas técnicas de levantamiento de patrimonio cultural existentes realizadas con escáner láser.Ítem Sale of profitable but unaffordable PV plants in Spain: Analysis of a real case(Elsevier, 2018-06) Lomas, J.C.; Muñoz-Cerón, Emilio; Nofuentes, Gustavo; de la Casa, JuanThe Spanish photovoltaic industry was stunningly successful during 2007–2010, fostered by a favourable feed-in tariff system. Nevertheless, the cost overrun of this promotion policy led to government legislation against existing PV plants. Although these investments will be profitable when the subsidy ends, according to the last law enacted in Spain (IRR = 7.4%), either a massive sale to vulture funds or the abandonment of PV plants is being planned. Owners are unable to cover the loans through which they were originally financed. In this scenario, investors find it more profitable to cancel all operational expenditures and allocate this working capital to cover their loans, although this measure implies a 22% energy reduction. This study analyses a representative Spanish PV plant based on real energy and economic data. The analysis shows the turn from an attractive IRR = 10.14% to a situation with limitations where the owner injects money annually to overcome potential bankruptcy of the investment. This paper reflects the influence of promotion policies in the profitability of PV plants. Additionally, the adverse legal framework in Spain identifies a profitable but unaffordable scenario, highlighting the differences between the economic and financial performance of a PV investment.Ítem A new method for the automated design of cooling systems in injection molds(Elsevier, 2018-06-19) Mercado-Colmenero, Jorge Manuel; Rubio-Paramio, Miguel Ángel; Márquez-Sevillano, Juan de Juanes; Martín-Doñate, CristinaThis paper presents a new method for the automatic design of the cooling system in injection molds, based on the discrete geometry of the plastic part. In a first phase the new algorithm recognizes the discrete topology of the part, obtaining its depth map and detecting flat, concave regions and slender details which are difficult to cool. The algorithm performs an automatic analysis of the heat transfer, taking into account functional parameters, in order to guarantee a uniform cooling of the part. Based firstly on the limit range distance from which the horizontal straight channels lose cooling effectiveness and secondly on the depth map data, the algorithm provides an optimal layout for the cooling system of the part by adapting it to its geometry. By means of adapting the precision of the algorithm to the molded geometry, both horizontal straight channels for low concavity areas and baffle matrixes for concave regions are used. In a second phase, the parameters of the cooling system such as channel diameter, channel separation etc, are dimensioned by means of genetic optimization algorithms. A second genetic optimization algorithm ensures uniformity and balance in the layout of the cooling system for the plastic part. The result is the design of the cooling system for the plastic part with the same performance as the conformal system. A constant distance between the cooling channels and the part surface is maintained, and at the same time the manufacturing of the mold using CNC techniques and traditional metal materials could be achieved. Complementarily, the algorithm performs an interference analysis with other parts of the mold such as the ejection system. The method does not need a subsequent CAE analysis since it takes into account functional and technical parameters related to heat transfer in its design, thus ensuring its functionality. The algorithm is independent of the CAD modeler used to create the part since it performs a recognition analysis of the part surfaces, being able to be implemented in any CAD system. The data obtained in the design can be used additionally in later applications including the automated design of the injection mold.Ítem Virtual and Augmented Reality: Applications for the Learning of Technical Historical Heritage(Wiley, 2018-07-18) Rojas-Sola, José Ignacio; Aguilera-García, ÁngelThis manuscript presents two applications developed for learning about the details and operation of Agustín de Betancourtś machine for cutting cane and other aquatic plants in navigable channels and rivers, drawing on virtual reality for personal computers under Windows, and augmented reality for mobile devices based on Android, along with a 3D printing of the 3D model. Similarly, in the case of augmented reality, an algorithm for the selection of parts or systems has been developed that shows the technical information of each piece or system of this historical invention. Finally, the evaluation of these applications has been satisfactory according to the results of an anonymous survey with seven questions given to a group of 10 people because the values obtained from statistical variables such as the mean, median and standard deviation prove it.Ítem Projective geometric model for automatic determination of X-ray-emitting source of a standard radiographic system(Pergamon-Elsevier Science LTD, 2018-08-01) García-Ruesgas, Laura; Álvarez-Cuervo, Rafael; Valderrama-Gual, Francisco; Rojas-Sola, José IgnacioBackground and objective: Currently, many orthopedic operations are planned by analyzing X-rays. The exact position of the focus is needed to calculate the real size of an object that is represented in conical projection, although in practice, this position is difficult to determine using current X-ray commercial systems. In this paper, a new geometric model is proposed in order to determine accurately, practically, and economically the location of the emitting source of commercial imaging systems using a single standard X-ray image. Method: The method requires a specific reference locator object to be positioned in the visual field of radiographic image. Because this object cannot implement ideal geometric points, but instead works with small spheres, it was necessary to experimentally validate the proposed methodology. The implemented software that was developed to validate the model was used in four series of tests. In these tests, we studied the influence on the final result of: 1. the selection of a specific set of markers in radiography, 2. the focus position variation in relation to radiograph and 3. the possible rotated angle of locator object about Z axis. Results: The results for 164 tests that were performed with this software showed that the expected error for 99.5% of values ranges with maximum error of [-0.35%, +0.39%], which shows that the model is independent of the design of locator object and its position and orientation in the radiographic field. The software used to validate the proposed model has been found useful to verify its reliability, effectiveness, ease of implementation, and accuracy. Conclusions: This model is effective to calculate the precise position of the X-ray focus of any standard radiographic system accurately.Ítem Agustin de Betancourt’s Mechanical Dredger in the Port of Kronstadt: Analysis through Computer-Aided Engineering(Multidisciplinary Digital Publishing Institute (MDPI), 2018-08-10) Rojas Sola, José Ignacio; De la Morena De la Fuente, EduardoThis article analyzes the first self-propelled floating dredging machine designed and executed by Agustín de Betancourt in 1810 to dredge the port of Kronstadt (Russia). With this objective, a study of computer-aided engineering (CAE) has been carried out using the parametric software Autodesk Inventor Professional, consisting of a static analysis using the finite element method, of the 3D model which is reliable under operating conditions. The results have shown that the system of inertia drums proposed by Betancourt manages to dissipate the tensions between the different elements, locating the highest stresses in the links of the bucket rosary, specifically at the point of contact between links. Similarly, the maximum displacements and the greatest deformations (always associated with these points of greater stress), are far from reaching the limits of breakage of the material used in its construction, as well as the safety coefficient of the invention, confirming that the mechanism was oversized, as was generally the case at the time. This analysis highlights the talent of the Spanish engineer and his mastery of mechanics, in an invention, the first of its kind worldwide, which served the Russian Empire for many years.
