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.
