Transient Temperature Field Analysis of Vehicle Disc Brake Based on Finite Element Method

Shoune Xiao

Abstract

Density of heat flow rate equation of trail vehicle disc brake surface is deduced according to energy conservation principle, and considering characteristic of air acting on disc brake during braking a method of coefficient of heat trasfer along with variation of vehicle velocity is put forth. A three-dimension model of vehicle disc brake is constructed.Transient temperature field of disc brake is analyzed in the case of emergency braking and constant velocity braking at the long slope.
