摘　　要：提出由农业机械工作部件的CAD模型建立其离散元法分析模型,在此基础上实现CAD软件与离散元法性能分析软件的集成,从而构建一种与散粒物料相互接触作用的农业机械工作部件的通用数字化设计方法和集成分析设计软件的思想。介绍了该数字化设计方法和集成分析设计软件的体系结构和主要功能,概述了在建立该方法和软件方面存在的问题及研究工作进展情况。This paper presents a novel method to establish the oneself analyzing model of the Discrete Element Method (DEM) based on the Computer Aided Design (CAD) model for the working parts of agricultural machine, then to implement the integration between CAD software and the DEM analyzing software for analyzing the performance of the working parts of agricultural machines which are contacted with granular material at working, and establish an universal method of digital design and an integrated software for designing and analyzing the working parts of agricultural machines. In this paper, the framework and the function of the method and the integrated software were introduced, the problem and development in the research were reviewed.
