Abstract: In order to overcome the problems of low accuracy of wear analysis results and long-time of wear prediction existing in traditional methods, a numerical simulation analysis method for material wear of a vehicle brake device based on finite element simulation is proposed. The friction coefficient of vehicle braking device wear is calculated, and the relationship between braking force and friction is obtained. On this basis, a finite element simulation system is established, and the stress variation law of material wear of vehicle braking device under braking state is analysed by using finite element method, and the numerical simulation of material wear of vehicle braking device is completed. The experimental results show that the accuracy of this method is between 96.3% and 98.7%, the missing detection rate is always less than 35%, and the minimum time of wear numerical simulation is only 0.23 s.
