Analyzing the Causes of Tread Damage in Metro Vehicles

摘要

This paper makes a detailed investigation, analysis, and research on the problems of tread abnormal wearing in the process of metro vehicles running. This paper analyzes the basic physical performance of brake shoes, according to the friction and wear test, measuring the material granularity of brake shoes using Tyler standard screen, and so on, and focuses on how to design brake shoes according to different operating conditions, to evaluate the thermal load of wheels under service braking condition during vehicle operation, to solve the problem of vehicle tread damage.
