Abstract

This thesis presents the design and analysis of a student competition based formula style racing car named as Formula Varsity. The goal and target of this project are to design, analyze and fabricate a new space frame chassis which are based on rule and regulation of Formula Varsity 2010. This event organized by Universiti Teknikal Malaysia Melaka. The race car chassis design was developed using CATIA V5R16 CAD software and commercial grade A36 low carbon steel was chosen as the material for the chassis construction. The chassis was later analysed for its structural performance using similar software. Results show that the new chassis design has higher maximum torsional stiffness of 4874.50 Nm/deg compared to the previous UTeM 2010 race car chassis with maximum torsional stiffness of 4415.189 Nm/deg. The new chassis design was also 39.5% lighter than its predecessor. The findings reveals that the new chassis design can provide higher power to weight ratio compared to the previous UTeM race car while in the same time gives better structural strength, thus giving the needed advantage in winning the event.
