The method of thermal calculation of automotive disc brake assemblies

Abstract

The article describes a method for calculating the heating temperature of the automobile brake disc. The brake disc is considered as a finite set of "cells" located in several layers. In thermal calculation, according to the proposed method, the heating of the disk surface is taken into account not only from the absorption of the vehicle kinetic energy, but also from the generated electric currents that cause micro-explosions between the irregularities of the disk surface and the brake pads. The cooling of the disk during the time between braking due to heat exchange with air is also taken into account. This method provides the ability to calculate the temperature of the brake disc, both on its surface and inside.
