Piezoelectric liquid inertia vibration eliminator

摘要

A vibration isolator comprising:
a piston (1605) resiliently disposed within a housing (1603) with a first set of seals (1607);
a mount plate (1609) configured for attachment to a vibrating body, the piston being connected to the mount plate;
an upper fluid chamber (1611) and a lower fluid chamber (1613), each being defined by the housing, the piston, and the first set of seals;
a tuning port (1620) for fluid communication between the upper fluid chamber and the lower fluid chamber;
a tuning fluid disposed within the upper fluid chamber, the lower fluid chamber, and the tuning port; and
a piezo piston (1619) resiliently disposed with the housing, the piezo piston being configured to be driven by at least two piezoceramic actuators (1623).
