Influence of the Pad's Material Properties on the Thermal Stresses during Braking

Abstract

A three-element model of a braking process for a tribosystem consisting of semi-space, sliding with the time-dependent velocity (braking at uniform retardation) on a surface of a strip deposited on a semi-infinite foundation is considered. The dependencies of temperature and thermal stresses on thermophysical properties of the materials, the time of braking, and the strip thickness were studied. It was proved that there is a possibility of applying the obtained results to modeling of a thermal cracking of frictional elements during braking.
