Random Vibration Analysis of a Nonlinear System Using the Volterra Series
نویسنده
چکیده
The Frequency Response Function (FRF) of a nonlinear system under white Gaussian ezcitation is computed up to O(P2) in the power spectral density of the input P. The FRF qualitatively shows the ezpected shifts in resonant frequency and supports the observed fact that FRFs from fandam excitation are returned as lkar system FRFs by the Hzlbert transform test.

متن کاملNonlinear Vibration of Functionally Graded Cylindrical Shells under Radial Harmonic Load
In this paper, the nonlinear vibration of functionally graded (FGM) cylindrical shells subjected to radial harmonic excitation is investigated. The nonlinear formulation is based on a Donnell’s nonlinear shallow-shell theory, in which the geometric nonlinearity takes the form of von Karman strains. The Lagrange equations of motion were obtained by an energy approach. In order to reduce the syst...
