遗传算法在空间对接机构优化设计中的应用

The Application of Genetic Algorithm in Space Docking Mechanical Optimization

空间对接机构是实现载人航天器空间交会对接的关键系统。捕获锁作为对接机构的组成部件,具有实现两航天器间捕捉和释放的功能。为避免传统的优化方法容易陷入局部最优的缺陷,优化求解捕获锁锁舌弹簧机构设计过程中的多目标、多自变量、多约束的问题,文章采用惩罚函数法和随机顺序配对机制改进标准遗传算法,使得改进后的遗传算法能进行全局寻优,且收敛性好。应用改进后的遗传算法,最终解决了捕获锁锁舌弹簧机构的优化设计问题。

Space docking mechanism is an important portion to realize the space docking between aircrafts.As a key component of the docking mechanism,capture latches are used to carry out following actions: capture and release.In order to solve the problem of local optimal results caused by traditional optimization method,this paper used publish function and stochastic tactic distribution model to improve the standard Genetic Algorithm.After improvement,the reformative Genetic Algorithm can find out optimal results an...
