| Abstract: | Recently,nonlinear random vibration problems have aroused universalattention.An improved non-Gaussian moment method for random vibration ofweak and strong nonlinear systems is presented in this paper.Compared with thenon-Gaussian moment method in Refs.[2,3],it has many advantages,for example,simple in calculation and suitable to more general nonlinear systems.The accuracyof its calculation is as nearly the same as that of the method in Refs.[2,3]. |
