摘要：

针对飞机翼身对接过程中，叉耳式交点接头因装配变形而发生干涉的问题，提出基于关键点距离检测的装配干涉判断方法.根据对接前叉耳接头上的现场实测数据，计算接头在装配坐标系下的位姿并建立耳型接头和叉型接头的坐标变换关系，通过投影方法计算并归纳出接头的距离极值点，求出叉耳接头间最小距离.综合考察各个叉耳接头处的最小距离，判断干涉情况，提出在多种叉耳接头布局方式下的机翼位姿调整方案.该方法将三维距离问题转化为有限个点的检测问题，能够快速实现在任意机翼位姿下的翼身对接干涉检测和机翼位姿修正.仿真验证结果表明该方法的有效性.
Abstract:

A detection method based on key points distance was proposed for the interference problem of the fork-ear joints due to the assembly deformation in the wing-fuselage joining process. The positions and orientations of the fork-ear joints in the assembly coordinate system were calculated and the coordinate transformation relationship between the ear joint and the fork joint was established according to the data measured before joining process. The distance extreme point was calculated and summarized while the minimum distance between the joint was obtained by using the projection method. Then, the detection results were determined and the alignment of wing position and orientation in various fork-ear joint layouts were provided by synthesizing the minimum distances of all fork-ear joints. The method can convert the 3D distance problem into finite point detection problem, and quickly realize the interference detection of wing-fuselage connection and alignment of position and orientation. The simulation results show that the proposed technology is validated.
