摘　　要：以飞机起落架静强度试验为研究对象,将光纤应变测量、电阻应变测量同时应用于试验,验证了光纤应变测量在飞机结构中的有效性。将试验结果与数值仿真计算结果进行对比分析,结果表明光纤应变测量与传统电阻式应变片测量趋势一致,且与数值仿真计算结果也较符合,可以应用于结构静强度试验的应变测量,验证了光纤应变在飞机机体结构静强度试验中的有效性和可行性。Taking the static strength test of the aircraft landing gear as the research object,the optical fiber measurement and the resistance strain measurement were applied to the test at the same time,which verified the effectiveness of the optical fiber strain measurement in the aircraft structure,the validity and feasibility of optical fiber strain in the static strength test of airframe structure.
