Abstract
In this paper, a bi-stable nonlinear energy sink (BNES) with buckled beam is developed to suppress the vibration of unbalanced rotor system. The structure of the BNES is developed. The specific structures and working principles of the buckled beam are introduced. Based on these, the dynamic equations of the rotor-BNES system are established. Then, the transient and steady state responses of the rotor-BNES system are numerically studied and compared with the linear visco-elastic damper. In addition, the vibration suppression ability and frequency suppression range of the BNES are analyzed. Finally, experiments are carried out and compared with the simulations to confirm the vibration suppression effectiveness of the BNES. The numerical and experimental results show that the designed BNES has a strong vibration suppression effect on the rotor system and can withstand a wide range of energy.
