The mechanism of interface heat generation during friction braking is analyzed. Considering the thermal characteristics of the organic friction material with temperature variation and the thermal resistance between the contact interfaces, the temperature field of the disc brake is analyzed by using the finite element method of the interface element, which avoids Pre-distribution of heat flow for the temperature field to improve the reliability of the analysis.
