摘要
飞机结构的使用寿命取决于使用方法,实施单机寿命监控能够有效地体现出这种差异性。基于飞行参数监控的思想,综合考虑了计算精度和计算效率,对不同采样率和不同滤波门槛值的影响进行了分析,确定了适用的采样率和门槛值;综合分析了不同情况下外挂质量对损伤计算结果的影响,为飞机结构实施单机寿命监控提供了技术保障。
The life of aircraft structure depends on its manipulating methods, and individual aircraft fatigue life monitoring is an effective way to reflect the difference. Based on the theory of flight data monitoring, the influences of different sample rate and different threshold were analyzed in detail by considering its efficiency and precision, and the sample rate and threshold for certain aircraft were proposed. The influence of different suspension weights on calculation result of damage was discussed. The purpose was to provide theoretical basis for individual aircraft fatigue life monitoring.
