| Abstract: | In this paper,a digital simulation of random process and the nonlinear transient response analysis module of MSC/NASTRAN are combined to acquire the random response of nonlinear system under random excitation.This method is applied to the analysis of a typical test piece (a rectangular cantilever plate).The calculation and random vibration experiment are finished in this paper.The results are satisfactory. |
