摘要 在分析组合夹具拼装特征的基础上,将基于实例推理原理引入组合夹具计算机辅助拼装中,进行了基于实例推理原理的组合夹具实例描述模型、拼装实例库建立方法、组合夹具自动拼装设计流程等问题的研究。建立了一种新的典型路径存储实例的方法,以实现对组合夹具新实例的快速存储。提出了按照组合夹具拼装的特征参数和权重进行相似实例检索的方法,该方法可以较好地实现对组合夹具实例的快速检索。在此基础上,开发出了组合夹具计算机辅助拼装系统,并应用实例验证了该系统的有效性。 Based on the analysis of modular fixture's features,Case Based Reasoning(CBR) was introduced into computer aided system of modular fixture.The research such as the case description model of modular fixture,the construction method of case and the automatic assembly design procedure of modular fixture based on case reasoning were studied.In addition,a new method of typical path case storage was built to achieve the rapid storage for new case of modular fixture.According to the feature parameter and weight of modular fixture's assembly,a case searching method was proposed to achieve the quick searching of modular fixture case.On these basis,a computer aided assembly system of modular fixture was developed,and the effectiveness of the system was demonstrated in practical operation.
