Abstract: In order to solve the problems of low accuracy and long time-consuming of traditional methods in analysing the wear characteristics of spraying material layer of multi-axis CNC machine tool hydraulic equipment, a research method of wear characteristics of spraying material layer of multi-axis CNC machine tool hydraulic equipment based on discrete element method was proposed. The discrete element method was introduced to analyse the wear characteristics of spraying material layer of multi-axis CNC machine tool hydraulic equipment. Based on the discrete element method, the contact model of spraying material layer of multi-axis CNC machining hydraulic equipment was established. The friction coefficient and wear rate of multi-axis CNC machine tool hydraulic equipment spraying material layer under different load and sliding speed analysed. The experimental results show that the accuracy of the proposed method is up to 99% and the analysis time is about 7 s.
