| 摘 要： | 通过分析组成装配体的零件特征,提出了连接结构的概念.采用面向对象技术,以连接结构作为装配信息的载体,对不同类型的连接结构的装配信息,采用相同的层次结构进行组织和存储.以连接结构作为基本装配单元,建立基于知识的装配Petri网模型,运用连接结构知识,构建装配Petri网模型,从而大大减少模型中的节点.在此基础上,利用Petri网点火原理,求解装配体的基于连接结构的可行装配序列.连接结构知识的引入可以降低装配序列规划的复杂性,提高装配顺序规划的效率.

| Abstract: | By analyzing the features of assembly's parts,concept of connecter-structure was proposed.With the object-oriented methodology,different connecter-structure's information were organized and stored with the same arrangement structure. Taking connecter-structure as the basic assembly cell,assembly model with Knowledge-Based Petri Net(KBPN) was constructed.Owing to the imported connecter knowledge,nodes of the mode were reduced drastically.Then,firing theory was used to get all feasible assembly sequences of t... |
