Paper Abstract

This paper presents a formulation for the optimal design of MR dampers. MR materials are suspensions of magnetically soft particles in a hydraulic medium. The application of intense magnetic flux to these materials gives rise to a fibrated microstructure which, when sheared, resists flow with yielding and viscous mechanisms. The yield stress is controllable by the magnetic field and is completely and immediately reversible when the field is removed. Controllable MR dampers utilizing MR materials entails a magnetic circuit consisting of a coil and low-permeability magnetic material to contain and guides the magnetic field.
