Vibration Reduction of Beam Structure using Squeeze Mode ER Mount

압착모드형 ER 마운트를 이용한 보 구조물의 진동저감 해석

To reduce unwanted vibrations in war ship which may be transmitted through underwater path, it is required to use high damping mounts to isolate the vibration. In this work, the beam structure with squeeze mode ER mount is proposed and response characteristics such as acceleration and force transmissibility of beam with constant voltage and optimal controller are experimentally analyzed. The controller is empirically realized and control responses are evaluated in frequency domains. Experiments show vibration reduction capability of squeeze mode ER mount.
