摘要: 在对配合精度要求较高的产品(或部件)进行装配时,为了得到它的最优装配组合,运用网络流规划建立了一种特定装配关系的选配模型,通过合理定义模型网络的中间点、弧的容量和方向以及模型的一般约束条件,将最优装配组合的问题转化成网络最大流问题。结合关联图模型和产品层次装配模型的特点,建立了一种便于选配模型求解的装配模型,采用了分层自底向上的选配方法,利用选配模型进行局部选配最终获得最优解。并通过实例对上述方法进行了验证。

Abstract: During the process to assemble the product or assembly which requires the high precision of the cooperation, to get the optimal assembly combination, a matching model is built based on the specific assembly relation by using network flow programming. After setting the proper mid-points and the proper capacity and direction of arcs in the model’s network and defining the general constraint of the model, the problem to get optimal assembly combination is transformed to the problem to get the maximum flow of network. Combining the relationship graph model with the hierarchical assembly model of product, a new assembly model is constructed to apply easily the matching model, and according to the hierarchical and down-top matching method, the optimal result is figured out after applying the matching model to match locally the parts of assembly. Moreover, the method above is proved by an example of application.

Key words: Assembly combination, Assembly model, Hierarchical and down-top, Match, Maximum flow of network
