摘　　要：复杂三维模型轻量化是节约存储空间、加快处理速度和实现信息隐藏的有效途径.为了快速有效地生成装配体的轻量化模型,提出了一套面向装配的复杂模型轻量化算法框架及处理流程,以零部件抑制、基于特征缝合的模型表面处理和模型整体抽壳等关键技术为手段,实现了复杂装配模型几何与结构的简化表示.该算法已顺利地运用到相关企业的装配设计,模型轻量化效率比较高,为复杂装配模型的网络协同设计和运动仿真等后续应用提供了一种有益的途径.Lightweight is an effectual way to save the storage space, quicken the processing speed and hide the secret information for complex 3D models. Related system architecture and processing workfiow are proposed in this paper for the lightweight of complex assemblies in a rapid and effective way. Key technologies such as com- ponents suppression, surface processing and shell extraction are taken as the cardinal means for this simplifying aim. The algorithm has been successfully applied for the assembly design in several enterprises, which proves to greatly improve the efficiency. The method of lightweight introduces a useful thinking for the applications as collaborative design and motion simulation, etc.
