The concept of linear systems with random coefficients is used to obtain an analytical approximation of the power spectral density (PSD) function of the response of an oscillator with non-linear inertia, damping and stiffness terms. To identify the parameters involved in the non-linear terms, a proc

A probabilistic treatment of the vibration field generated by the random vibration of flat plate components is proposed herein. This treatment is based on the computation of the frequency-averaged spatial correlation coefficient of the plate normal displacement. This spatial correlation coefficient
The results of an experimental investigation of vibration field spatial correlation carried out on two flat plate structures and on a car body shell are presented herein. The main purpose of this investigation was to assess the validity of the theoretical spatial correlation model presented in part
ลฝ 4 . Numerical experiments with a nonlinear x oscillator which has its harmonic frequency changing randomly with time reveal certain interesting features of its dynamics of quantum evolution. When s 0, the level populations are seen to oscillate. But, as the ลฝ . nonlinear coupling is switched on )
