Abstract

Abstract The effectiveness of railway brakes is highly dependent on the thermal condition of the brake disc and friction linings. An effective research method for the heat transfer process in brakes was computer simulation and experimental tests on a full-size dynamometric test bench. A two-dimensional, axially symmetric numerical model of transient thermal conductivity in a railway brake was presented. Appropriate boundary conditions of the problem were applied, describing the heat generated in the brake and discharged to the environment. The problem was solved using the finite-element method. This article presents exemplary results of the brake temperature calculations obtained using the numerical model and the results of experimental tests carried out on two types of brake discs.

铁路盘式制动器在测功机架上的传热过程的数值与实验分析

摘要铁路制动器的有效性在很大程度上取决于制动盘和摩擦衬片的热状况。在全尺寸测功台上进行计算机模拟和实验测试是研究制动器传热过程的一种有效方法。建立了铁路制动器瞬态导热系数的二维轴对称数值模型。应用了问题的适当边界条件，描述了制动器中产生并排放到环境中的热量。这个问题是用有限元法解决的。本文介绍了使用数值模型获得的制动器温度计算的示例性结果以及在两种类型的制动盘上进行的实验测试的结果。
