A study of the seismic response reduction has been conducted on the single-sided vibro-impact track NES. Firstly, the derivation of formula deduction and optimization can be achieved of the single-sided vibro-impact track NES system when attached to a three-degree-of-freedom main body structure. Secondly, numerical simulations of the SSVI track NES system are to be carried out by impulsive loading and seismic action respectively, followed by a comparison with the tuned mass damper (TMD), orbital nonlinear energy well (track NES) and the locking system. The research results show that the SSVI track NES exhibits an improved robustness performance compared with that of the tuned mass damper (TMD), with its energy robustness better than that of the track NES system, thus verifying its good seismic properties.
