摘　　要：在复杂产品的生产过程中,装配占有相当大的成本比重,对产品质量影响显著。提出1种基于建模核心ACIS和图形引擎HOOPS的装配仿真系统,有别于传统的依赖于CAD平台的装配仿真环境,其模型兼容性强,功能容易拓展。算法库、标准件库和工艺实例库的引入,使复杂产品的工艺规划得到算法、数据和知识的综合优化。对系统实现的关键技术进行了探讨,提出了统一装配建模技术,讨论了基于工艺知识的工艺规划。初步实现了一个装配仿真原型系统,并以减速箱为例进行了装配建模和工艺规划的简单验证。Complex products’ assembly process, which costs much in the whole manufacturing, has a great effect on products’ quality. An assembly simulation system based on modeling kernel ACIS and physic engine HOOPS was proposed, which is independent on CAD software and has strong model compatibility and good module expansibility. During the procedure of assembly process planning, optimal solution could be got by comprehensive utilization of related algorithms, data and knowledge because the framework of the system contains algorithms library, standardized components library and process cases library. A unified assembly information model was proposed, and assembly process planning based on assembly knowledge was discussed. A prototype of the proposed assembly simulation system was developed, and a simple case was given to illustrate assembly modelling and assembly process planning.
