Airborne platform vibration environmental spectrum data processing via bootstrap method
GJB/ Z 126-99 The inductive methods for environmental measured data of vibration and shock implemented in 2000 only applying to solve the problem of normal distribution data.However,the actual vibration environmental spectrum data may not follow normal distribution assumption.The authors in this paper focus attention on a new statistical induction method of bootstrap sampling.This method would overcome the problem of requiring a big sample size and typical probability distribution.Then,power spectral density (PSD) upper probability limit of vibration environmental spectrum data was given by this method.The calculation results indicate this method has high reliability at a given confidence level.
