摘      要：A novel vibration isolation device called the nonlinear energy sink(NES)with NiTiNOL-steel wire ropes(NiTi-ST)is applied to a whole-spacecraft *** NiTi-ST is used to describe the damping of the NES,which is coupled with the modified Bouc-Wen model of *** NES with NiTi-ST vibration reduction principle uses the irreversibility of targeted energy transfer(TET)to concentrate the energy locally on the nonlinear oscillator,and then dissipates it through damping in the NES with *** generalized vibration transmissibility,obtained by the root mean square treatment of the harmonic response of the nonlinear output frequency response functions(NOFRFs),is first used as the evaluation index to analyze the whole-spacecraft system in the *** optimization analysis of the impact of system responses is performed using different parameters of NES with NiTi-ST based on the transmissibility of ***,the effects of vibration suppression by varying the parameters of NiTi-ST are analyzed from the perspective of energy *** results indicate that NES with NiTi-ST can reduce excessive vibration of the whole-spacecraft system,without changing its natural ***,the NES with NiTi-ST can be directly used in practical engineering applications.
