Parameter identifications of the Hydraulic Mount

A lumped parameter model is proposed for analysis of dynamic behaviour of a Passive Hydraulic Engine Mount (PHEM) with incorporation of inertia track and throttle, which is characterized by effective and efficient vibration isolation behaviour in the range of both low and high frequencies. Most of the model parameters, including volume compliance of the throttle chamber, effective piston area, fluid inertia and resistance of inertia track and throttle are identified by experimental approach. The advantage of the methods proposed in this paper is accurately abstained the parameters in the initial design stage, thus the mount design time is greatly reduced.
