Application of Genetic Algorithm in the Layout of Fixture Components

Automation in the layout of fixture components is important to achieve efficiency and flexibility in computer aided fixture design. Based on basic genetic algorithm and particulars of different fixture components, a method of layout space division is presented. Such techniques as suitable crossover rate, mutation rate and selection arithmetic element are adopted in the genetic operation. The results show that genetic algorithm can effectively be applied in the automatic layout of fixture components.

基于蚁群算法的民用飞机设备架智能布置设计研究

传统的基于流程的民用飞机设备架总体设计工作,需要设计师借助结构和系统数字样机经过反复协调迭代形成设备架布置方案,严重依赖于设计师的工程经验,方案迭代速度慢且方案的优劣评价较难量化,这对飞机研制周期和整机经济性都有较大的影响。本文对蚁群算法状态转移规则、搜索路径优化、信息素更新等开展研究,完成设备架智能位置规划算法设计;并基于React组件化优势,完成设备架智能布置可视化开发;最后将设备架智能布置算法和前端UI结合,完成民用飞机设备架智能布置系统V1版本的研究设计,设计师可在操作页面一键运行算法,设备架布置方案计算完成后自动在页面展示,也可根据设计需要将计算结果导入CATIA开展数字样机设计。
