多细节层次装配模型及序列规划

摘要/Abstract

摘要： 为了建立支持自顶向下的产品设计系统，开发一个自顶向下设计的装配模型和相应的高效、快速的装配规划方法，通过深入分析自顶向下的设计流程，提出了支持自顶向下设计的多细节层次装配模型。该模型中的超零件模型和简化零件模型是对装配体细节的不同描述，是装配体中零件几何信息的简化表达。利用多细节层次模型，对自上而下、分层分步的装配序列规划以及装配序列规划算法和复杂性进行了分析。应用实例表明，该方法避免了装配规划中复杂模型的庞大数据量问题，可以提高装配规划的推理效率，加快装配仿真中的碰撞检测速度，使装配规划的结果更加合理和实用。

Abstract: To build a top-down design supporting system, an effective assembly model for top-down design and its efficient algorithm of assembly planning were developed. After analyzing the process of top-down design, an approach to build the product model at multiple levels of detail (LOD model) for top-down design was presented. In this LOD model, the super-component model and the simplified-component model were the simplified representations of different complex assemblies. A novel approach was proposed to generate assembly sequences layer upon layer, and step by step. The computation complexity of assembly planning was reduced dramatically due to efficient simplification of the model and the obtained assembly sequences were more feasible and practical.

Key words: assembly model, assembly sequence planning, conceptual design, model simplification
