摘要：
The magneto-rheological (MR) fluid damper is a type of controllable fluid damper that has been employed to control the vibrations in building structures, vehicle suspensions, etc. In this paper we present an analysis of three types of working modes for MR fluid dampers, flow mode, shear mode, and extrusion mode. Further, a calculation model of the damping force in the shear flow mode is established. The design of a novel MR fluid damper, including the sealing structures, is presented, and a set of test systems was built to investigate the mechanical performance. The results provide a theoretical and experimental basis for the application of an MR fluid damper.
