Abstract
Embodiments of a vibration isolation system are provided. In one embodiment, the vibration isolation system includes a first isolator having opposing mounting interfaces, a tuning spring disposed between the opposing mounting interfaces, and a piezoelectric actuator disposed between the opposing mounting interfaces and coupled in series with the tuning spring, as taken along a first load path through the first isolator. A controller is operably coupled to the piezoelectric actuator. During operation of the isolation system, the controller varies a control voltage supplied to the piezoelectric actuator to dampen vibrations transmitted through the first load path.
