面向概念设计的拆卸序列生成方法研究

Study on Disassembly Sequence Planning Method for Conceptual Design

为了缩小产品拆卸序列筛选范围,简化拆卸序列计算方法,最终获得合理的目标拆卸序列,将骨架概念模型引入自顶向下产品设计过程中。骨架模型还包含了支持可拆卸分析的工程语义信息;将产品层次关系用无向图来表示,基于无向图转化所得的邻接矩阵、拆卸工程语义集合和骨架模型,快速准确地生成拆卸序列,实现产品早期研发阶段的可拆卸分析。

In order to narrow the product disassembly sequence screening range,to simplify disassembly sequence, and acquire the reasonable disassembly sequence ultimately,the skeleton conceptual models are introduced into the top-down process of product design in this paper. The basic functional-structural information and engineering semantic information which can support the disassembly analysis of products are included in the skeleton model. The product hierarchical relationship is represented by the undirected graph. Through the adjacency matrix which is transformed by undirected graph, disassemble semantic information and the skeleton model, the reasonable disassembly sequence can be acquired concurrently in the design phase of the conceptual design. Finally,this method is used in the bogie design of a high-speed train to verify its feasibility.
