摘要
针对航天复合材料舱体结构变形给自动化装配工序带来的干涉、零件位置相对偏移等问题,引入矢量排队概念并提出了基于三步迭代调姿的补偿方法,采用基于全局定位的相移条纹投影测量方法进行网格筋蒙皮结构型面测量、大视场环境下的点云高精度拼接及型面计算提取,之后对变形量进行补偿和关键信息调整、程序修正,最后通过典型复合材料舱段进行了验证,满足产品装配自动化需求和精度要求.
Abstract
In order to solve the problems of interference and relative position deviation caused by the deformation of aer-ospace composite compartments structure to the automatic assembly process,the vector queuing concept was introduced and it was proposed that a compensation method based on three-step iterative attitude adjustment.The phase shift fringe projec-tion measurement method based on global positioning was used to measure the grid bar skin structure profile,and finish high-precision point cloud splicing and profile calculation extraction in a large field of view environment,and then the deform-ation amount was compensated,key information was adjusted and the program was corrected.Finally,the test was verified by a typical composite material compartment to meet the requirements of product assembly automation and accuracy.
