612 Fundamental research on application in the vibration response control of MR damper

Abstract

Research and development of the variable damper using magnetorheological fluid (MR damper) is carried out in the fields with various, brakes, clutch, and vibration response control system etc. The rheological properties of the fluids can be changed dramatically by applying a magnetic field, and this behavior can be applied to control dynamic properties of some building structures. In this paper, the fundamental characteristic was grasped by the dynamic loading tests. And, the shaking table test by one-degree-of-freedom system was carried out, and performance and controllability of the MR damper were verified.
