Abstract
One of the popular types of formula car chassis is space frame chassis. There are many issues to design and analyze formula car chassis. For driver, Front and side impact are the main issue for design and analysis with accurate and safety. In this article, the 2017-2018 formula SAE (the Society of Automotive Engineers) rules are used for analysis. SolidWorks 2016 are used to construct the CAD models of formula car chassis. Finite element method (FEM) is used to analyze the CAD models using SolidWorks Simulation. The results show that all formula car chassis models satisfy the 2017-2018 formula SAE rules. For the front impact, the maximum stress and the maximum deflection are not significant affected by varying the distance of the side members. While varying the distance of the front impact members affects both of the maximum stress and the maximum deflection. For the side impact, the maximum stress and the maximum deflection are not significant affected by varying the distance of the front members. While varying the distance of the side members affects both of the maximum stress and the maximum deflection. The criterions of the formula car chassis design are to make maximum stress lowest and maximum deflection lowest. The distance of the front members joint and the distance of the side member joint should be as low as possible.
