A brief description about designing of Magnetorheological (MR) damper are described. MR dampers are semi-active suspension devices that use MR fluids to produce a controllable damper. The mechanical properties of the suspension can be controlled by adjusting the yield stress of the MR fluid. In this book, the design development for a new mixed mode MR damper with combination of shear and squeeze working modes was carried out. The magnetic field generated by electromagnetic coils in MR damper was analyzed using finite element method. The MR damper was designed and fabricated based on the...

Magnetorheological elastomer (MRE) isolators are semi-active seismic restrained devices that utilised elastomeric materials to produce controllable stiffness. The existing passive conventional isolator is not efficient in various ground motions, while the laminated MRE isolator is only flexible horizontally. An innovative new concept of the MRE isolator differs from that of the laminated steel-rubber layered isolator presented in this research. The study focuses on a new MRE isolator designed by adopting the engine mounting concept based on the electromagnetic circuit simulation studies. The...
