Hydraulic engine mounts hydro mounts are passive devices used to isolate automobile engine vibration from the chassis at different automobile operating conditions. In this paper we introduce a semi-active hydro mount using Magneto Rheologic MR fluids. A semi- active hydro mount can be used to optimize the mount performance for a wider range of vehicle operating conditions. The MR fluid mount developed and mathematically modeled in this work can change its yield shear stress once under a magnetic field and hence, it may be tuned by applying electromagnetic field. The tuning ability allows us to vary the natural frequency of the mount and to increase the damping of the mount. To verify the numerical results an experimental test bed has been developed. Preliminary results show that the experimental and numerical results correlate well.
