Whole-Spacecraft Vibration Suppression Based on Negative Stiffness Inertial Nonlinear Energy Sink
In this paper,the negative stiffness element is integrated into the inertial nonlinear energy sink to form the negative stiffness inertial nonlinear energy sink(NS-INES),and this device is applied to suppress the vibration of the whole-spacecraft.Based on the reduction percentage of the maximum ampli-tude,the vibration suppression performance of the NS-INES is shown.Meanwhile,the influence of neg-ative stiffness elements on the vibration suppression performance of inertial nonlinear energy sink is dis-cussed by comparison.Finally,the influence and optimization of the parameters are discussed.The re-sults show that the new NS-INES acting on the Whole-spacecraft has good vibration suppression per-formance.
