This document summarizes a seminar presentation on stress analysis of a heavy duty vehicle chassis using finite element analysis (FEA). The presentation covers the methodology used, which includes modeling the full-scale chassis in CATIA, applying a uniform load distribution in ANSYS, and analyzing stress distributions and deformations. The results show maximum von Mises stresses of 200.67 MPa and deformations of 8.15mm between frame members. Modifications to the cross-section dimensions and connections are suggested to reduce stresses and deformations at critical points and increase chassis life.
