- 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.
