Experimental determination of thermal stresses disk brakes in depending from the braking pressure and vehicle speed

Abstract

The goal is that during the process of braking stopping distance as short as possible, which is one of the important parameters of braking. During the braking process itself, a certain heat is generated on the brake disc and brake pads, which depends on the speed of movement that the vehicle had at the time of the brakes, as well as from the realized pressure in the brake installation. The purpose of this work is to find optimal braking parameters, in order to generate as less heat as possible on the disc brakes. The paper presents experimental research on a test rig BRAKE DYNO 2020, for a simulated vehicle speed of 100 km/h when the braking pressure of 2.8 MPa and 5 MPa. It is concluded that higher temperatures occur in the case when the braking pressure is 2.8 MPa, because it takes more time to stop. The results of this research can be applied in practice, in defining braking pressure.
