A Review on Thermal and Structural Analysis of Disc Brakes in Motor Vehicles
Abstract: Braking is a technique that turns kinetic energy in a vehicle into mechanical energy that must be dissipated as heat. The frictional heat created at the disc-pad interface can cause high temperatures during the braking period. Thermal elastic instability (TEI), early wear, brake fluid vaporisation (BFV), and thermally stimulated vibrations can all be caused by frictional heat created on the rotor surface (TEV). In this research, a vehicle's solid type …
