Abstract
The active vibration mount disclosed herein employs a multiplicity of layers of an electro-strictive material such as an electro-strictive polyurethane film interleaved with electrodes. A majority of the layers are employed as an output transducer while at least one layer is employed as a sensor generating a force-induced voltage. Accordingly, a feedback controller responsive to that voltage can energize the output transducer thereby to reduce the vibratory force transmitted through the mount over a preselectable range of frequencies while the mount supports a static load.
