在 F-4B 和 F-8E 飞机上,对挂飞状态下的响尾蛇导弹 AIM-9D 进行了振动响应测量。导弹悬挂在 LAU-7/A 发射架上,加速度计固定于导弹和发射架的不同位置,其信号被记录在磁带上。对这些信号进行数字分析,得到了不同飞行条件下的功率谱密度曲线。画出了典型的自相关函数曲线和振动的均方根加速度值随动压变化的曲线。一般说来,导弹的响应是宽带随机振动迭加一些正弦波分量,频带宽度在2.5kHz 范围内。 On the F-4B and F-8E aircraft, the response of the rattlesnake AIM-9D in the flying state was measured. The missiles were hung on LAU-7 / A launchers, the accelerometer was fixed at different positions on the missile and launcher, and the signals were recorded on the tape. Digital analysis of these signals gave power spectral density curves for different flight conditions. The curves of typical autocorrelation function curves and vibrational rms acceleration values ​​with dynamic pressure are plotted. In general, the response of the missile is a random vibration of broadband superimposed with some sine wave components, the bandwidth of 2.5kHz range.
