Transient temperature field analysis of disc brake braking process

For disc brakes, the heat dissipation performance of the brake disc during the braking process directly affects the safety of automotive braking. Use COMSOL Multiphysics 5.6 to numerically simulate the friction heat generation and heat dissipation process of disc brakes during braking. Simulate the transient braking process of heating and convective cooling to find the minimum interval between a series of braking actions to avoid excessive temperature caused by delayed continuous braking cooling and degradation of braking efficiency. Import the temperature field solution results into the solid mechanics solution process, and finally solve to obtain the thermal strain results of the disc brake, and preliminarily explore the reasons for uneven wear of the inner and outer brake pads.
