摘要
通过研究标准连接件对拆卸约束的影响,提出基于连接件知识的规则推理方法,并将其与现有的几何推理方法相集成,实现了对拆卸约束的自动生成。应用设计零件特征数据处理、零件接触约束生成、基于连接件知识推理的优先约束生成、基于几何推理优先约束的生成及拆卸约束图形处理五个主要系统模块,在Autodesk Inventor的二次开发平台上,应用VB.NET开发了产品拆卸约束自动生成的原型系统,并经实例验证,说明应用该系统自动生成拆卸约束是有效可行的。
Studies the disassembly constraint relationships between common machine elements and standard connectors. A novel rule-based reasoning mechanism on standard connector-knowledge is then proposed, which is integrated with an existing geometrical reasoning method to realize auto-generation of disassembly constraints. A prototype system is developed on the platform of Inventor API(Application Programming Interface) and VB programming language on Visual Studio 2005. It consists of five modules:part feature data processing, contact constraint processing, connector-knowledge reasoning, geometric reasoning and disassembly constraint graph processing modules. A case study is involved to indicate the feasibility and efficiency of the Auto-generation of disassembly constraints using the proposed approach.
