Abstract
A hydraulic mount apparatus () for supporting a vibration source is disclosed. The mount apparatus () includes a housing () that defines a housing chamber () separated by a partition assembly () into a pumping chamber () and a receiving chamber (), each containing a magnetorheological fluid (). A flexible body () is partially disposed in the pumping chamber () for deforming elastically in response to vibrations caused by an external excitation. A fluid passage () extends between the pumping chamber () and the receiving chamber () for passing the fluid therebetween during low frequency vibrations. A piezostack actuator () partially extends into the pumping chamber () for moving within the pumping chamber () for varying the volume of the pumping chamber () to prevent a pressure increase in the pressure chamber to substantially cancel relatively high frequency vibrations.
