Abstract

In this paper, we perform a theoretical analysis to determine the quantitative relationship between abrasive wear and crack initiation in a brake drum when a wheeled vehicle is braking. Using the model of a rough friction surface, a closed system of algebraic equations that allows one to study cracking in the brake drum depending on the abrasive wear of the friction surface is constructed. The developed model is shown to allow calculating the effect of wear on crack initiation in the brake drum in the design stage.

制动鼓裂纹萌生模型

摘要

在本文中,我们进行了理论分析,以确定轮式车辆制动时制动鼓中磨料磨损与裂纹萌生之间的定量关系。使用粗糙摩擦表面的模型,构建了一个封闭的代数方程组,该系统可以根据摩擦表面的磨料磨损来研究制动鼓中的裂纹。显示出开发的模型可以在设计阶段计算出磨损对制动鼓中裂纹萌生的影响。
