Abstract: In order to overcome the problems of low simulation accuracy and long time in traditional numerical simulation method of vehicle brake disc wear temperature field, a numerical simulation method of vehicle brake disc wear temperature field based on SIFI characteristics is proposed. The temperature field simulation model of vehicle brake disc wear is built, and the temperature field estimation results are obtained. On this basis, after the Gaussian scale space is generated by using SIFI features, the key point descriptor is generated by determining the key extreme points and the direction of the key points, so as to extract the characteristics of the vehicle brake disc wear temperature field. According to the feature extraction results, the numerical simulation of the vehicle brake disc wear temperature field is carried out. The experimental results show that the simulation accuracy of this method is more than 92%, the average simulation time is 33.9 ms, and the comprehensive performance is better.
