Abstract

This paper presents the system of equations of heat dynamics of friction and wear (HDFW) for the pad–disc tribosystems, accounting for the thermal sensitivity of materials and the dependence of the friction coefficient on the maximum temperature of the friction surface. The contact of two sliding layers with heat generation due to friction is chosen for simulation in the formulation of the corresponding thermal problem of friction. The solution to the HDFW system of equations is obtained using the method of lines. The calculations are performed for a cermet pad and a cast-iron disc. The variation in such interdependent characteristics as temperature, velocity, and friction coefficient is investigated in the braking process.

计算盘式制动器温度模式时考虑材料热敏性和摩擦耐热性的方法

摘要

本文介绍了摩擦片和摩擦片系统的摩擦磨损热力学方程组（HDFW），其中考虑了材料的热敏性以及摩擦系数对摩擦表面最高温度的依赖性。为了模拟相应的摩擦热问题，选择了两个滑动层与因摩擦而产生热量的接触。HDFW方程组的解是使用线法获得的。对金属陶瓷垫和铸铁盘进行计算。在制动过程中研究了温度，速度和摩擦系数等相互依赖的特性的变化。
