A detailed mechanical model of a double pumper fluid mount

Conventional passive elastomenc mounts have been used as noise and vibration isolators in the automotive and aircraft industries for many years. For even better noise and vibration isolation, passive fluid mounts have been replacing elastomeric mounts in both the automotive and aerospace industries during the past few years. With more increase in the popularity of fluid mounts, it is important to characterize the dynamics of the fluid mounts more accurately. Many papers have been published on the modeling of these devices, but mostly on single pumper fluid mounts. In this paper, we focus on double pumper fluid mounts. The intent of this paper is to develop a very detailed model of a double pumper fluid mount including all dampings.
