Random vibrations of Duffing oscillator with nonlinear elastic characteristic of exponential type
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2010, Vol 7, Issue 2
Abstract
We present a method for estimating the power spectral density of the stationary response of Duffing oscillator with nonlinear elastic force of exponential type. The method is based on the idea that a nonlinear system may be replaced by a linear system by minimizing the mean square error of the two systems. An equivalent linear system is derived, from which the power spectral density is deduced.
