Vibration isolation using a magnetorheological damper in the squeeze-flow mode

摘要

Magneto-rheological (MR) fluids are rapidly rising in prominence as a means of producing controllable damping devices for vibration control. MR fluids can be used in various modes of operation in order to provide damping forces. One of the least exploited of these modes is commonly known as squeeze-flow, where large, controllable forces can be generated over relatively small displacement ranges. In this paper the authors describe a recently constructed test facility in which an MR squeeze-flow device is incorporated as the damping element in a vibration isolator.
