机电产品多层次模块划分方法

摘要

分析了机电产品在进行模块划分时的多层次特性,并提出了机电产品多层次模块划分方法.提出基于产品BOM对机电产品进行高级模块的划分,通过构建产品结构树并对其结点进行模块划分与否的判定.提出了基于最小最大划分的机电产品低级模块划分方法,首先给出模块的初步划分和计算最小最大模块,然后给出了子模块的关联度的计算方法,最后得到低级模块的划分.最后以轮式装载机为例来说明该方法的合理性和有效性,并给出了轮式装载机的一级模块和二级模块的划分结果.%A multi-level modularity method is proposed based on the multi-level character analysis of mechanical and electrical products.Advanced module gained based on Bill of Material{BOM)and product structure tree(PST)beingconsisted of node(part or parts)is formed.Primary module is gained by min-max partition modularity method, and demonstrates the relevant definitions and calculation methods of the initial partition, min-max partition and submodule relevancy.At the end, this method is applied to wheel loaders to demonstrate its rationality and effectiveness.
