摘　　要：全机静力试验中,每个工况对应不同的应变测量规模,并且静力试验周期长,将所有应变片全部接入到测量设备上,会导致设备利用率极低。针对上述问题,本文提出了一种飞机主体结构应变分组以及飞机主体结构加非主体结构A+B的应变测量优化方法,能够使设备利用率最大化,从而解决型号任务多的时候应变测量设备不够的问题。In the full scale aircraft static test,each working condition corresponds to different strain measurement scale,and the static test cycle is long,so connecting all strain gauges to the measurement equipment will result in extremely low equipment utilization.A strain grouping method for aircraft main structure and an optimized strain measurement method for aircraft main structure with non-main structure(A+B)are proposed to address the above issues,which can maximize the equipment utilization rate,so as to solve the problem of insufficient strain measurement equipment when there are multiple model tasks.
