摘要：
This paper examines the nature of the statistical distribution of the peak maximum amplitude of the forced response of a mistuned bladed disk. A range of values of the structural coupling between blades and the standard deviation of mistuning have been used, and it is determined if it is correct to describe the distribution of the peak maximum amplitude as Weibull. Also, using a neural network, a functional relationship between the peak maximum amplitude distribution and input parameters (structural coupling between blades and standard deviation of mistuning) is sought via coefficients of Hermite polynomials and 99 percentile peak maximum amplitude.
