Abstract

The design of a chassis contains all necessary components to support loads of the car and the driver. A formula varsity race car chassis have different parts, among them are chassis base. In this project the goal is to optimize the chassis base using HyperWorks software. Furthermore, optimization have different methods but in this project the method are used is topology optimization. Second chapter in this report is about literature review of competition regulation, chassis design, types of material, stiffness torsional and optimization method. Then, the methods are used along conducted this project are shown in the third chapter. These projects basically use Catia software to develop CAD data and HyperWorks software to do analysis. Only linear static analysis is conducted in this project to identify the maximum displacement and maximum von mises stress of the model. The basic idea of this project is the load prediction come from the weight of the driver which is 1000N and the constraint at front and rear wheel side. In HyperWorks software, linear static analysis can only be done in Radioss or OptiStruct. Besides that, OptiStruct also act as a solver for optimization problem. The objective of optimization in this is minimum the compliance. After done the optimization process, the way to valid the optimized design with make comparison between the existing model and optimized design. Lastly, the percent are obtained from displacement reduction is 52 % and the von mises stress reduction is 53%.
