摘　　要：文中介绍一种应用于制动夹钳单元、踏面单元等制动器的可靠性试验台。试验台满足UIC 541-01标准,可完成纵向±2.5°倾角的疲劳试验。同时,基于六自由度平台设计,试验台可模拟制动盘或车轮相对构架±10 mm的横向位移、绕垂向±1°转角及模拟垂向盘片摩擦等工况,模拟车辆运行极限状态,能够对新制动器进行累计不少于100万次的制动、缓解疲劳试验。This paper introduces a reliability test-bed applied to brakes such as brake clamp unit and tread brake unit.The test bench meets UIC 541-01 standard and can complete the fatigue test with longitudinal inclination of±2.5°.At the same time,based on the design of the six-degree-of-freedom platform,the test bench can simulate the working conditions such as±10 mm lateral displacement of the brake disc or wheel relative to the frame,±1°angle around the vertical direction and friction of the vertical disc,simulate the vehicle operation limit state,and can conduct braking and fatigue relief tests for the new brake for a total of no less than 1 million times.
