Thermal stress effect on disc brake rotor for NGV vehicle

The concept of braking system may seem fairly obvious which is to stop the vehicle. Potential energy of the vehicle converts into heat due to frictional contact between the brake pads and the brake disc. The heat needs to be dissipated properly to the surrounding to avoid any failure from occurs. In order to get better understanding on temperature distribution and stress of the disc brake during braking operation, steady state and transient response are introduced. There are two types of disc brakes design being studied, which are straight vane and curved vane and the analysis is applied on normal passenger NGV vehicle. The findings of this research provide a useful design tool and improve the brake performance of disc brake system.
