摘　　要：归纳了原始机构的拓扑构造特性,运用图论理论得到了原始机构的拓扑缩图。通过对机构的原始拓朴缩图进行二度点的分配,消去同构方案后,即可综合出符合条件的拓扑全图和一系列相对应的运动链图谱。在此基础上指定各构件和运动副的类型,得到与原始机构具有相同或相似功能的新型机构。设计者可根据功能要求和具体的设计环境,从中筛选出好的结构。Characteristics of topology constitution of the original structure are extrapolated and the topological contracted chart can be obtained by use of graph theory.After two-degree-point allocation of the original topological contracted chart and the elimination of isomorphic representation,the topology total graph that meet conditions and series of graphs of kinematic chain can be derived.At base of the above,new-type mechanism that has the same functions as the original one can be obtained when define the form of every components and kinematic pairs.According to the functional requirement and the specific design circumstance,designers can select the optimizational structure among them.
