落地铣镗床虚拟装配序列规划与优化

Boring and Milling Virtual Assembly Sequence Planning and Optimization

采用基于层次向、属性向和关系向的多视图方法对TK6813大型落地铣镗床进行装配建模。采用新型SAP树结构建立了TK6813大型落地铣镗床装配序列模型,以SAP树中A,AP节点以下的数据子节点为研究对象,通过分层搜索,运用模糊综合评价法来确定各数据子节点的相对装配优先关系,进而判断所有子数据节点的装配顺序。根据宽度优先的分层搜索原则,完成A向AP和S向SP的转变,从而实现TK6813大型落地铣镗床装配序列的优化。

Based on the hierarehy,properties and multi-view approach to the relationship,modeled TK6813 boring and milling.With the new SAP large tree structure to establish TK6813 boring and milling assembly sequence model.Studied A,AP following data node of SAP tree.By hierarchical search,applied fuzzy comprehensive evaluation method to deter～ne the data sub-node relative assembly precedence relationships,then determined the order of all the subassembly data nodes.Breadth-first search based on hierarchical principles,completed transforming A to AP and S to SP,then achieved large-scale optimization of TK6813 boring and milling assembly sequence.
