Simulation analysis of train disc brake temperature field

Abstract

Simulation calculation of temperature field of train disc brake system under 500r/min fixed speed condition is carried out by using the software ABAQUS. The result shows: the heat quantity generated by braking firstly forms tailed area using friction radius as center; with continuous development of braking process, annular temperature distribution is formed, and finally, surface temperature area of brake disc displays spotted. The temperature of brake pad rises quickly. When braking begins 2.5 seconds, the temperature reaches extreme. With extension of braking process, surface temperature begins diffusing to peripheral and thickness directions until it ends. The temperature field distribution obtained by simulation calculation of finite element model provides effective reference for design and engineering application of brake disc and brake pad. © the authors.
