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.
