摘　　要：针对某型战斗机机翼多组双耳片孔中心距离的测量问题,提出激光三角法测量方案。采用两个激光位移传感器,结合余弦定理实现空间两点距离的非接触式测量。同时设计一种靶球装置,该装置直接安装在耳孔上,用一个红宝石测头表示双耳孔的位置信息,结合半径补偿从而准确测量出双耳片孔中心距离。经验证,该方法测量快速、准确,工作效率高,并且可以实现在机测量,满足了某型战斗机机翼多组双耳片孔中心距离的测量要求。To solve the problem of measuring the center distance of multiple sets of binaural holes of a fighter wing,a laser triangulation measurement scheme was proposed.Two laser displacement sensors,combined with cosine theorem,was adopted to achieve non-contact measurement of the distance between two points in space.Meanwhile,a target ball device was installed in the ear hole with a ruby probe indicating the position information of the binaural hole and a vcombined radius compensation of the target ball measureing the center distance of the binaural hole with accuracy.The experiment results verify that the method is fast and accurate in measurement with high operation efficiency and can achieve on-board measurement qualified for the standards of the center distance of multiple sets of binaural holes for a fighter wing.
