摘要:
制动器是保障商用汽车行驶安全的核心零部件，为解决制动过程中其动态性能的测试难题，运用ANSYS仿真模拟试验的分析方法，研究了制动鼓在紧急、多次重复和连续等多工况制动条件下的制动力和摩擦热对制动鼓的耦合作用。结果表明：紧急制动时制动鼓内表面易出现高温闪点；重复制动时制动鼓温度和应力都比较大，会造成制动效能下降和裂纹生成；持续制动时高温会引起等效应力增大，并可能出现热衰退现象。
Abstract:
Drum brake is the core component to ensure safety of commercial vehicles. In order to solve the problem of dynamic performance in braking process, the coupling effect of braking force and friction heat on the brake drum under the braking conditions of emergency, repetitive and continuous braking was studied using ANSYS simulation method. The results show that it is prone to appear high temperature flash point on the inner surface of the brake drum under the emergency braking condition. Under the repetitive braking condition, the temperature and the stress of the brake drum are relatively large, which will cause decrease of the brake performance and crack generation. And under the continuous braking condition, the high temperature will cause the equivalent stress to increase, and it is possible to appear the heat fade.
