On energy transfer between vibrating systems under linear and nonlinear interactions

Abstract

The present study deals with energy transfer in a dissipative mechanical system. Numerical results are given by considering two different potentials and periodical excitation. Specifically, we show energy transfer from linear oscillator to another one, depending on initial conditions. Also, energy transfer from linear to nonlinear ( energy pumping), as well as from nonlinear to linear, oscillator is analyzed, under linear and nonlinear interactions.
