LM가이드형 면진테이블의 진동응답 저감효과

This study evaluated the effects of vibration response reduction by seismically isolated table using the linear movable guide. Considering the floor response spectra at the installed location, a set of shaking table tests were performed to review the response acceleration, the displacement response, and load-displacement relation curve. The test results showed that the seismically isolated table using the linear movable guide reduced 51 ~ 86% of the response acceleration although the relative displacement of the system was beyond 5㎜. As higher location of the seismically isolated table and larger peak acceleration of seismic motion, the horizontal force and the deformation were increased.
