英文摘要：

This paper developed a software for simulating conveyor working process and fulfilling performance analysis, based on discrete element method. The software can simulate the dynamic working process of the conveyor depending on CAD model （CAD software design） in the design stage of the conveyor. By changing the conveyor CAD model, we can analyze the performance evaluation of different structures and dimensions of the conveyor, thereby implementing optimization of the conveyor structure and size parameters,which provides a new method and new means for the conveyor research and design.
