Abstract
Each vehicle has a different chassis shape and specification, including a sports car. A car must meet several criteria such as comfort, safety, and with a sporty appearance. Before being made, a design process is carried out and analysis is conducted to quantify structural responses, e.g., von-Mises stress test, strain, displacement, reaction force, and safety factor based on the static loads. This research had been produced using an Autodesk Fusion 360 and analysis uses the Finite Element Analysis (FEA). A series of main discussions are directed to examine applied material on the Ford GT40 chassis. After the FEA-based simulation, the maximum displacement is found to be 0,441 mm, von-Mises stress of the chassis is 181.7 MPa with the safety factor 1.14. It indicates that the chassis can hold 548.9 N vertical load still deform elastically and still under allowable material properties. Steel material is suitable for safety and comfort factor of a Ford GT40 sport car.
