Researches of a Magneto-Rheological Fluid Damper with External Coil Based on Electromagnetic Finite Element Analysis

Article Preview

Abstract:

In vibration control field magneto-rheological (MR) fluid dampers are semi-active control devices that have recently begun to receive more attention. This paper presents a new type of MR fluid damper with external coil. The new structure of the damper was optimized and analyzed based on a static magnetic analysis with the help of electromagnetic finite element analysis (FEA) using the software of ANSYS. The damping characteristics of the damper were theoretically researched. Research results show that the designed MR fluid damper with external coil has wider scope of damping adjustment and strong energy-dissipating ability. The study method in this paper and the obtained results will help designers to create more efficient and reliable MR fluid dampers.
