Quasi-zero stiffness system has been widely used to isolate structural vibrations. However, its small dynamic stiffness may result in drastic low-frequency vibration. This is a curse of employing quasi-zero stiffness systems in engineering. In this paper, a nonlinear energy sink (NES) is used to ove...
