Abstract:In view of the poor energy robustness of track nonlinear energy sinks (track NESs) and poor frequency robustness of tuned mass dampers (TMDs), a proposal has thus been made of single-sided vibro-impact track nonlinear energy sinks (SSVI track NESs). Firstly, a theoretical analysis has been carried out of SSVI track NES, followed by the performance optimization and numerical simulation of SSVI track NES under impulse excitation. The research results show that the SSVI track NES exhibits a superior performance in vibration reduction under impulsive excitation, demonstrating a high robustness against the change of input energy and frequency.
