Abstract

A MRF engine mount on the basis of existing hydraulic mount is designed, After that, an expression of liquid damping with the current change under the valve mode model is derived. Mathematics modeling of MRF mount is built up, and frequency changing expression of MRF mount´s dynamic stiffness and damping lagging angle is deduced. Then I simulate the dynamic characteristics within low frequency using MATLAB and do the parametric research. Especially, the influence of current intensity upon dynamic characteristics is analyzed.
