Braking system is one of the safety aspects in vehicle design that is very important to stop a vehicle safely and avoiding an imminent collision with another vehicle, person or obstacle. During braking operation, most of the kinetic energy is converted into thermal energy and thus increases the disc temperature. Excessive temperature with poor heat dissipation would causes problems such as cracking, coning and brake pad failure. Therefore it is important to have sound knowledge on temperature distribution and thermal stress so that the designed brake will fully function. This study was conducted with a focus on the effect of thermal stress and temperature distribution behaviour on ventilated disc brake with various loading of the NGV vehicle. Steady state and transient response are used to predict the temperature distribution, deformation as well as stresses during the worst and extreme braking condition. Finite element analysis approached is conducted to identify the temperature distributions and behaviours of disc brake rotor in steady state and transient response. ANSYS software is used to perform the thermal analysis and predict the temperature distributions and behaviours at various loads. Results from both steady state and transient response are compared so that the result will assist the automotive industry in developing optimum and effective disc brake rotor.
