| Abstract: | 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. |
