为避免在复杂产品装配序列规划过程中出现过度的组合爆炸,同时基于产品无向连接图和子装配体约束要求,提出一种新的子装配体识别方法。通过产品零件的无向连接图,找出复杂产品中的“连接关键件”和“识别关键件”,用于区分不同的零件连接集合;通过子装配体的稳定性检验及矫正、独立无冲突性检验及矫正,找出复杂产品中的有效子装配体;采用深度搜索策略生成每个子装配体的装配序列,得到复杂产品的装配树结构。通过某齿轮油泵模型的实例演示,证明了子装配体识别方法的有效性。

In order to alleviate the combination explosion problem in the process of complex product assembly sequence plan-ning,base on the connected undirected graph and the subassemblies constraints,a new subassembly identify algorithm is proposed.The “connection key part”and “identify key part”are found by the connected undirected graph to distinguish be-tween the different part sets.All effective subassemblies of the complex product are found out by the stability and independ-ence without conflict of the subassembly.Then the depth search strategy is used to generate the part assembly sequence of each subassembly,and get the assembly tree structure of the complex product.The demonstration of gear-oil-pump assem-bly proves that the new subassembly identify method is effective.
