摘　　要：该文提出模拟一种弹射冲击加载方法,能够有效地模拟飞机弹射起飞瞬间的传载情况。通过在飞机机体结构上根据传力路径布置传感器,利用无人机的结构监测系统采集的试验数据,分析无人机在模拟弹射冲击测试下的振动响应情况。根据冲击试验和飞行数据分析的结果,得到冲击试验与飞行测试数据的加速度时间历程曲线基本一致,验证提出的弹射加载方法的合理性与有效性。A method for simulating ejection impact loading is proposed,which can effectively simulate the load transfer situation at the moment of ejection and take-off.By arranging sensors on the aircraft body structure according to the force transmission path,and using test data collected by the structure monitoring system of the drone,the vibration response of the drone under the simulated ejection impact test is analyzed.According to the results of impact test and flight data analysis,it is obtained that the acceleration time history curves of impact test and flight test data are basically consistent,which verifies the rationality and effectiveness of the proposed ejection loading method.
