载荷谱飞行实测振动环境谱数据处理研究

通过开展飞机振动环境谱的飞行实测,获取飞机设备舱、管路、部分飞机结构等振动环境情况,经过数据处理获取能够反映飞机实际使用下的振动环境数据,给出了典型任务剖面的功率谱密度处理结果,为飞机耐久性/损伤容限优化设计提供依据,进一步提高飞行的安全性和可靠性。

Study on data processing of vibration environment spectrum of load spectrum in flight measurement

As to carry out the vibration environment spectrum of aircraft flight test,and obtain the aircraft equipment tank,piping,part of the aircraft structure vibration environment situation,through data processing to obtain can reflect the actual use of the vibration of the environmental data,durability/damage tolerance optimization design for aircraft,further improve the flight safety and reliability.
