摘　　要：为实现飞机翼面标定试验中加载点载荷的最优分配,通过提高各加载点的受载均匀性,以压心距离误差为控制条件,对加载点的载荷进行了迭代优化。在满足飞机安全的前提下,该算法可最大程度地提高加载载荷,从而提高标定试验精度;实现了智能化载荷分配,杜绝了人为计算误差,提高了工作效率,并已成功应用于某型飞机机翼标定试验中。In order to optimize of loading-points loads allocation during calibration test of the aircraft wings,by improvement of the evenness of loading-points load,with using the distance between the loading-point and the center of pressure as control condition,iterative optimization of loading-points load was investigated.The results show that this algorithm can not only increase loading-points loads to the most extent,thus improving the precision of calibration test,but also make the loads allocation be intelligent,thus avoiding the error caused by manmade calculation and increasing the work efficiency.This algorithm has been successfully applied to the calibration test of some aircraft wings.
