Abstract
Recent years,social demand for high-performance anti-vibration device for machines and structures is growing as the performance of machines and structures have been improved.Generally,the performance of a passive vibration ilolator is improved by lowering the natural frequency of the system.Here,considering a passive isolator for vertical vibration,it is desired that the isolator possess the characteristics of high-static-low-dynamic-stiffness in order to keep low vibration transmissibility and avoid large static deflection.In this study,we propose a passive vibration isolator using the post-buckled L-shaped beam structure and examine restoring force,free vibration characteristics and the frequency response of proposed system.
