基于实例推理的装配顺序规划研究

摘要

研究装配实例表示与重用技术，针对装配顺序规划存在的问题，提出基于实例推理的装配序列规划方法。通过对装配知识的组织来构造装配实例模型；采用基于相似度的实例检索算法，对实例进行检索获得最佳匹配实例；根据推理结果进行装配过程仿真与评价，得到最终的装配序列。最后，开发相应的装配顺序规划与仿真模块，并以齿轮减速器为例，验证了方案的可行性。%The representation and reuse of as-sembly knowledge studied, and a case-based assembly sequence planning method is presented for the question in it. A method is proposed, which can construct case repre-sentation by organizing the assembly knowledge, and can adopt the similarity-based retrieving in case retrieval algo-rithm. The assembly process simulation is proposed based on the result of case-based reasoning. At the same time, a case-based reasoning and assembly simulation module is developed, and a certain kind of reducer assembly is used as example to examine the algorithm.
