摘　　要：为分析复杂运动方式机械部件与颗粒的接触作用,基于多刚体运动学(MBK)建立复杂运动方式机械部件的离散元法(DEM)分析模型,实现多刚体运动学与三维离散元法的耦合,在此基础上研制复杂运动方式机械部件与颗粒接触作用过程的仿真分析软件,实现与三维CAD软件的集成,开发一种集设计与性能分析为一体的CAE软件——AgriDEM。实例验证了该软件的可行性和有效性。To analyze the contacts between mechanisms with complex motion and particles,a discrete element method analysis model was presented for mechanisms with complex motion based on multi body kinematics.Basing on this method,multi body kinematics was coupled with three-dimensional discrete element method and the analysis software used for simulating the process of contacts between mechanisms with complex motion and particles was developed.And then integrating with the three-dimensional CAD software,the CAE software（ADEM）which combined the mechanism design and performance analysis evaluation was developed.The feasibility and efficiency of this software was preliminarily validated through examples.
