Resumen
In this paper, the analysis of the design of the single-cylinder steam engine of the Grasshopper
beam designed by Henry Muncaster in 1912 is shown. This engine was incorporated into ships
and railways and it was published in the Model Engineer journal in 1957. It shows great complexity
due to its ability to transform reciprocating movement into rotary movement and its high number of
elements (more than 150). To this end, a study of computer-aided engineering (CAE) was carried
out using the software Autodesk Inventor Nastran, consisting of a linear static analysis using the
finite element method (FEM) of the 3D CAD model under real operating conditions in order to learn
if it was well designed, according to material resistance criteria. The assembly is analyzed in the
two most unfavorable situations in order to determine the von Mises stresses, the displacements and
the safety coefficient distributions. Finally, it was found that the work pressure (maximum admissible
steam pressure in the admission) was 0.15 MPa.
