【摘要】 本文从装配的概念及发展现状、装配模型的建立、装配的评价体系等系统地阐述了产品虚拟装配的过程和重要性，并对虚拟装配的操作平台Pro／ENGINEER作了一个简单的介绍，针对Pro／Engineer CAD／CAM软件Assembly模块中不能体现装配路径及过程干涉的问题，提出了在组合件的Skeleton下规划装配路径和动态仿真、在Pro／Program的Relation下设定干涉条件和仿真程度、以及通过人机交互解决干涉的方法。并以专利产品低速电机的减速器为例验证了该方法。该方法具有可以直接利用Pro／Engineer固有功能的优点，但是目前还无法做到装配路径的自动规划。若与零件库(Family Table)相结合，还可实现零件组装的过程仿真、替换、干涉检验。更多还原

【Abstract】 Assembly model of the Pro/Engineer CAD/CAM does not support the interference check of assembly path and process. To resolve this problem, this paper put forward a method which directly takes advantage of the eigen functions of Pro/Engineer. That is: Planning path and simulating dynamically under Skeleton, Setting interference conditions and simulation degree under Relation of Pro/Program, realizing the interference check with the man-machine interchange. Samples is also given to prove it. Combined with Family Table, this method also can realize the process-simulation, replacement, interference check. However, the automatically planning assembly path can not been reached up to now.更多还原
