针对飞机强度试验中飞机结构损伤位置定位困难这一问题,采用基于时差(Time difference of Arrival,TDOA)的定位方法,比较了最小二乘法和最优化方法的定位效果,并对影响定位精度的因素进行了分析讨论,为工程应用提供理论依据。
Aiming at the difficulty of locating the damage location of aircraft structure in aircraft strength test, a positioning method based on Time Difference of Arrival (TDOA) is used to compare the positioning effect of least square method and optimization method. The factors influencing the positioning accuracy Carried on the analysis discussion, provided the theory basis for the engineering application.
