T he main parameters for the analysis of anisotropical performance w ere confirmed according to the previous hypothesis and tested experimentally . The results show that variety of the relative heights and the radius of MR elements affect the radial stiffness of MR isolator . When isolator w orks in radial direction, the linear mechanical characteristics are available. If there are several MR isolators w ith press
