Optimization for vibro-impact nonlinear energy sink under random excitation
文献摘要：
As a promising vibration control device,the vibro-impact nonlinear energy sink(VI-NES)gathered ex-tensively attention in recent years.However,general optimization procedures have not been available for the design of VI-NES subjected to random excitations.To this end,this paper constitutes a research effort to address this gap.Specifically,the approximate analytical solution of the system stochastic response is obtained in conjunction with non-smooth conversion and stochastic averaging methodology.Taking advantages of this approximate solution,the variance of the system is defined and easily minimized to calculate the optimal parameters for VI-NES.In addition,the results computed by this way fairly correlate with direct numeric simulations.
