Structural Analysis and Optimization of a Baja Vehicle’s Engine Support Using the Finite Element Method

Resumo

This work presents the structural analysis of the engine package in a BAJA prototype. Three distinct design configurations were evaluated: (1) the initial engine package; (2) the engine package without the firewall tube; and (3) the engine package without the vertical tubes. Simulations encompassed assessment of deformations, Von Mises stresses, combined tensile/compressive stresses, and buckling modes. All configurations demonstrated satisfactory performance, with high safety factors and stresses well below the yield strength of AISI 1020 steel, the material selected for its favorable mechanical properties, machinability, and widespread structural use in the automotive sector. Configuration (2) achieved a mass reduction of 1.04%, while configuration (3) reduced mass by 0.78%, both maintained the required structural integrity and performance for the intended application.
