Non-linear modeling and experimental study of a streamlined Passive Hydraulic Mount

A lumped parameter model is proposed for analysis of dynamic behaviours of a Passive Hydraulic Engine Mount (PHEM) with incorporation of inertia track and throttle, which is characterized by effective and efficient vibration isolation behaviours in the range of both low and high frequencies. The most of model parameters including volume compliance of throttle chamber, effective piston area, fluid inertia and resistance of inertia track and throttle are identified by experimental approach. The experiments are made for the purpose of validation of the PHEM. It has been shown by comparison of the numerical results with the experimental observations the present PHEM possesses of fairly good performance for vehicle industries.
