Abstract

Through analyzing the statistical properties of measured vibratory data for X-type aircraft, it confirms that non-Gaussian or nonstationary vibration environment exist in transportation and employment of equipments. The deficiencies of the existing vibration test methods and standard are pointed out, and the vibration test methods and flow chart based on measured data are proposed, which can effectively avoid the problem of over-test or under-test.
