Abstract

Formula Society of Automotive Engineers (FSAE) competition is a worldwide racing competition that allow the university students to develop and fabricate their own formula racing car with the practical skills and knowledge learnt throughout the academic years. Before the event started, every racing team must be confident as their racing car is well developed and well prepared. Sometimes the accident still possible to happen due to some uncontrollable factors such as weather, road condition and driver status. To prevent severe injuries to driver, the racing car must strong enough to provide a good protection. The main component that should be first to design when building a racing car is the chassis (space frame) as it plays the role as the outer shell for protection and the backbone to carry all component. Hence, the objective of this project is to design and analyze the space frame chassis for the frontal and side impact test. The design criteria for the space frame chassis is predicated to FSAE rule 2019 where the other factor like ergonomics, load analysis and safety factor are considered as well. Software used in this project for 3-Dimensional (3D) modeling and crash test simulation is Computer-Aided Three-Dimensional Interactive Application Version 5 (CATIA V5). Seven concepts had been proposed in this project by combining different component of chassis such as front bulkhead, main roll hoop, front roll hoop, side impact structure and bracing. The three best concepts were selected based on the criteria like chassis weight, material cost, manufacturability, safety and triangulation as stated in evaluation of the concept selection via weighted matrix decision method. The selected concept designs will be proceeded into the 3D modelling and Finite Element Analysis (FEA) using CATIA V5 to find out the best among three designs on protecting the driver from frontal and side impact. The value of von mises stress (N/m2), deformation (mm) and factor of safety will be discussed and used to identify the best design
