文章摘要: Hydraulic engine mounts are widely used in automotive powertrains for vibration isolation. A lumped mechanical parameter model is a traditional approach to model and simulate such mounts. This paper presents a dynamical model of a passive hydraulic engine mount with a double–chamber, an inertia track, a decoupler, and a plunger. The model is developed based on analogy between electrical systems and mechanical-hydraulic systems. The model is established to capture both low and high frequency dynamic behaviors of the hydraulic mount. The model will be further used to find the approximate pulse responses of the mounts in terms of the force transmission and top chamber pressure. The close form solution from the simplified linear model may provide some insight into the highly nonlinear behavior of the mounts. Based on the model, computer simulation has been carried out to study dynamic performance of the hydraulic mount.
