针对机构运动链进化设计中产生的同构体,以及传统同构识别方法中识别依据多为邻接矩阵与拓扑矩阵且不具备唯一性等问题,提出一种基于树状图的同构识别方法。制定编码规则,获得唯一树状图识别依据,并证明了识别方法的可行性;应用树状图同构识别方法优化机构运动链进化设计流程,依据优化设计流程分为输入、初始机构转化、综合、筛选、识别及进化结果选择与转化模块,建立结构化的机构运动链进化设计智能原型系统,为机构运动链进化设计提供一种工具化手段,并进行了实例验证。结果表明,机构运动链进化设计智能原型系统是可行、有效的。

Aiming at the problem that isomorphism generates in evolutionary design of mechanism kinematic chain,and the recognition basis in the traditional isomorphic recognition method is mostly adjacency matrix and topological matrix and does not have uniqueness,a method of isomorphic recognition based on dendrogram is proposed.The coding rules are formulated,a unique dendrogram identification basis is obtained,and the feasibility of the identification method is proved.The tree-like isomorphic recognition method is used to optimize the evolutionary design process of the kinematic chain of the mechanism.According to the optimized design the process is divided into input,initial institutional transformation,synthesis,screening,identification and evolution result selection and transformation modules.A structured mechanism motion chain evolution design intelligent prototype system is established to provide a tooling method for the mechanism motion chain evolution design and verification of examples is carried out.The results show that the intelligent prototype system of mechanism motion chain evolution design is feasible and effective.
