Numerical analysis of the thermal behaviour and performance of a brake system with temperature-dependent material properties

Purpose: The brake system is the most significant component of a vehicle because it protects the driver, passengers, other road users, and property on both sides of the road. The basic principle of the disc brake system depends on the friction-based between the brake pads and rotor disc. Design/methodology/approach: The paper introduced a developed 3D finite element thermal model of the brake system to simulate the heat generated by friction in the vehicle's disc brake. Findings: The results presented the surface temperature at any instant of the disc brake under various initial velocities when the materials properties of the rotor disc and pad depend on temperature. Research limitations/implications: The main aim of the present paper is to build a numerical model to simulate the braking process under various initial vehicle velocities and investigate the influence of the material properties when they function on temperature and constant. Originality/value: The maximum difference between the two cases (contact and depend on the temperature) was 17 K for the initial velocity of 144,120. Also, it was found out that the percentage differences of the surface temperature increasing with the rise in initial vehicle velocity were 323% and 392.5% when the initial velocity of the vehicle increased from 100 km/h to 144 km/h.
