Two-Mode Operation Engine Mount Design for Automotive Applications

Two-Mode Operation Engine Mount Design for Automotive Applications

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 ine...
