摘要
在飞机线束EWIS设计阶段中,线束综合成为飞机线束设计中非常重要的一环。线束的综合程度越高、全机综合线束数量越少越有利于线束的敷设安装与生产制造,更有利于后期的维护与改造升级。文中提出一种利用常用的Excel VBA脚本语言,对CATIA进行二次开发,通过全机可用敷设线束通道以及设备之间的互联关系,运用常用的Floyd最短路径算法,完成线束的最优路径规划。线束综合设计人员可以以自动规划出的敷设路径作为参考,结合EWIS在设计时需要遵循的规则,规划出线束的最短敷设路径。该方法有助于飞机EWIS线束综合设计以及减轻全机线束敷设质量。
In the design stage of EWIS for aircraft harness,harness synthesis has become a very important part of the design of aircraft harness.The more comprehensive the harness is,the less the number of integrated harness is,the more conductive to the installation and production of the harness,and the more conductive to the later maintenance and upgrading.This paper presents a method of utilizing Excel VBA language to redevelop Catia.Based on the available wiring harness channel and the interconnection between equipments,this method uses the commonly used Folyd shortest path algorithm to complete the optimal path planning of wiring harness.Wire harness integrated designers can take the shortest route automatically planned as a reference,andplan the shortest route of wiring harness according to the rules that EWIS needs to follow whendesigning.It is helpful to the comprehensive design of aircraft EWIS and to reduce the weight of the whole aircraft wiring harness laying.
