| مستخلص: | The low-frequency vibration environment of the C-5A cargo deck is defined in terms of the accelerations experienced during takeoff, cruise, landing, and turbulence simulated by low-altitude terrain following. The accelerations presented are the peaks and the percentage occurrence levels versus one-third octave frequency band from 0.4 to 31.5 Hz. These percentage occurrence curves allow the prediction of the probability of exceeding a given level of acceleration for a given flight profile. They can be used to develop vibration test curves for C-5A cargoes which are sensitive to low-frequency acceleration, such as large, flexible spacecraft and launch vehicles mounted horizontally. Sample calculations are presented which show two methods of predicting the probability of occurrence of given levels of acceleration for typical flight profiles, based on the Gaussian and the binomial distributions. |
