Abstract: Hydraulic engine mounts are applied to the automotive applications
to isolate the chassis from the high frequency noise and vibration generated by
the engine as well as to limit the engine shake motions resulting at low
frequencies. In this paper, a new hydraulic engine mount with a controllable
inertia track profile is proposed and its dynamic behavior is investigated. The
profile of the inertia track is varied by applying a controlled force to a
cylindrical rubber disk, placed in the inertia track. This design provides a
hydraulic engine mount design with an adjustable notch frequency location and
also damping characteristics in shake motions. By using a simple control
strategy, the efficiency of the proposed hydraulic engine mount in two-mode
operation meaning isolating mode in the highway driving condition and damping
mode in the shock motions, is investigated.
