摘要
干涉铆接是飞机装配的关键工艺之一,干涉量控制对提高铆接件的疲劳寿命有十分重要的意义。为准确控制干涉量,首先对铆钉尺寸进行基于视觉的快速测量;其次,分别采用传统等公差分配方法与基于果蝇选配方法对铆钉进行分组,并以匹配成功率和匹配质量作为评价指标进行评价;最后,自主研制一套基于果蝇算法的铆钉锪窝孔智能选配系统。与传统的等公差带分组相比,系统匹配成功率从76.84%提高到90.85%,配对质量从0.8927提高到0.9096。
Interference riveting is one of the key technologies in aircraft assembly.The control of riveting interference is very important to improve the fatigue life of riveted parts.Firstly,in order to control the interference accurately,the rivets were measured quickly based on machine vision.Secondly,the rivets were grouped by the equal tolerance and the group matching based on fruit fly optimization algorithm respectively.The matching rate and matching quality were used as evaluation indexes.Finally,an intelligent matching system for rivet and countersink based on fruit fly optimization algorithm was developed.Compared with the traditional equal tolerance zone grouping,the matching rate of the system is improved from 76.84%to 90.85%,and the matching quality of the system is improved from 0.8927 to 0.9096.
