Stress Analysis of Monocoque Chassis for Formula Student Electric Vehicle

The main purpose of this project is to design and optimize a monocoque chassis for the Oxford Brookes University for formula student electric vehicle 2019 -2020. The report background is established with the literature review about chassis design, monocoque composite material and torsional stiffness. The important chassis structure used in formula student race are explained to examine the advantages and disadvantages of each chassis structure. Design flexibility is considered to be the main factor for the chassis. Design is basically gradually developed and inspired from the OBR 2018/19 combustion vehicle chassis model. The model is designed with more compactable for aerodynamic and vehicle dynamic of the complete vehicle. The torsional stiffness is the most important measure for the stability of the chassis. Hence, a finite element analysis is carried out with the front suspension points. To acquire a simple manufacture without compromising the stiffness of the chassis, lay up optimization has been used for the chassis for each critical area of the monocoque. To ensure the feasibility of the torsional stiffness results, a three point bending test validation results has been enclosed. The design, FEA and validation are properly explained for the manufacturing process
