Abstract (Summary)

This work is a contribution to the design and optimization of a Formula SAE chassis for CSULB. A 3D CAD model of the previous chassis for CSULB was produced and modified to make it as rigid and lightweight as possible. The modified chassis was checked for static analysis using FEM as per SAE guidelines. Torsional stiffness of the structure was calculated by applying loads on suspension attachment points. The response of the structure under different load-cases and boundary conditions was analyzed on NX. The differences in the results were observed using 1D Beam and 2D Shell Elements. As an important design feature, five eigenvectors were calculated and the animations were shown, to study the overall dynamic behavior of the structure. Finally, an optimization was performed in order to maximize the torsional stiffness and minimize the chassis weight by minimizing tube thicknesses for different frame members avoiding failure in any loading condition.
