It develops a numerical simulation programming based on DEM（Discrete Element Method） for linear vibrating screen screening. Firstly, it introduces the program logic structure, and discusses for the impact parameter identification from the collision mode. In order to improve the calculation efficiency of numerical simulation, it uses CPU and GPU hybrid parallel computing method in this system. Finally, it shows the calculation results to verify the influence of parallel computing for the three - dimensional discrete element method numerical simulation.
