Abstract:Targeted energy transfer is investigated in non-conservative system with nonlinear energy sink. First we get the slow-flow dynamics of system based on the complex-averaging method. Then we obtain the approximate relationship between energy of system with structural parameters, get the necessary condition of damp which system can achieve targeted energy transfer. We also obtain the effective range of linear oscillator damp which nonlinear energy sink has the capacity of vibration suppression. At last the above analysis is verified by numerical simulations.
