Finite Element Analysis of a Space-Frame Chassis
This project aims to analyze a simplified space-frame chassis of a Formula SAE racecar. The finite element analysis will look at the maximum stress and displacement of the chassis with the mounted engine load and suspension pickup. Matlab and Abaqus were both used for the FEM solutions and the results from the two were compared. Results were very similar for displacement but some differences exist for the stress values as different ways of intepretations are used. I. Introduction Space frame chassis are commonly used in race cars. The goal of race car chassis is to be lightweight and rigid. As a space frame chassis utilizes a tubular design, it is convenient for prototyping and the suspension, engine, and body panels are directly attached to the chassis. The space frame is an idealized model of the structure built from rigid linked connected to freely rotating nodes and it tries to achieve a perfectly rigid frame. This project analyzes the maximum stress and displacem...
