A novelty style metal hydraulic engine mount (HEM) is developed. The HEM designed in this paper consists of hydraulic cylinder, bar, two pistons and the spring on the bottom. The mechanical model and the dynamic equations are set up by considering kinematics and continuous of fluid, and the analytical method for dynamic behavior including dynamic stiffness and transfer function of HEM are suggested herein. The dynamic characteristics of HEM are investigated. It is shown that the HEM proposed herein can be employed in the practical engineering for vibration reduction.
