Abstract
In this paper, the authors propose a vertical seismic isolation system consisting of four V-shaped links, torsion springs, hinges, a table board and a base board, which has bilinear spring force characteristic. This characteristic is effective in reducing the static deflection of the vertical isolation system. The resisting force characteristic and seismic responses of this isolation system were analyzed numerically. The trial isolation system was made, and the static and dynamic resisting force characteristics were measured. The seismic responses of a mass installed on the table board were measured using a vibration machine. The experimental results were compared with the calculated results and the effects of vibration isolation in vertical direction and the validity of the calculations were substantiated.
