Frequency domain properties of hydraulic bushing with long and short passages: System identification using theory and experiment
Several methods for the identification of bushing parameters (up to 50Hz) are suggested. Linear time-invariant models are proposed for a hydraulic bushing with two parallel flow passages. A model with only a long capillary tube passage (an inertia track) is examined. Peak magnitude and loss angle frequencies are analytically found.
