THE APPLICATION OF SPECTRAL ANALYSIS TO NONLINEAR RANDOM VIBRATIONS

The application of spectral analysis for nonlinear random vibrations is studies in this paper. The response spectrum for nonlinear random vibrations is obtained by introducing Hermite polynomial. The study indicates that it is possible to solve nonlinear vibration problems by using spectral analysis directly. It is not necessary to linearize the nonlinear terms in this method so that the errors introduced by linearization can be eliminated. This method provides a convenient and accurate tool for solving nonlinear random vibration problems.
