Study of Thermal about Braking Discs of FSAE Electric Racing Car

It is important to study the thermal of the braking disc when having the FSAE competition.In this paper, the heat of the braking discs is studied during the process of emergency braking and continuous braking by the theory of heat transfer and the theory of braking in order to estimate whether the temperature of disc is extremely hot and have failure or not.After that, heat transfer in solids modular of Comsol Multiphysics is used to have thermal analysis about the racing cars emergency braking condition and continuous braking condition, then have the temperature of the disc after emergency condition and duration condition.Finally, we validate theoretical calculation and provide theoretical basis for optimal design of disks.
