摘　　要：针对因成型误差引起的复合材料构件装配干涉问题,本文基于激光测量设备获取装配件点云数据,提出一种基于实测数据的复合材料构件装配干涉与间隙的降维求解方法,将三维装配的干涉与间隙计算转化为二维边界距离计算。以某型飞机雷达罩装配为例,通过实验验证了本文所提出的方法与算法的可行性,相较于原有装配工艺,装配精度与装配效率得到了提升。For the composite component assembly interference problem caused by molding errors,this paper proposed a method of dimensional reduction of composite component assembly interference and clearance based on point cloud data obtained from laser equipment,it converts the interference and clearance calculation of the threedimensional assembly into the calculation of the two-dimensional boundary distance.Taking a certain type of aircraft random assembly as an example,the feasibility of the proposed method and algorithm is verified through experiments,and the assembly accuracy and efficiency are improved compared with the original assembly process.
