Abstract
A compliant structure, such as a rubber pad, is used to simplify the resonance pattern of a vibrating object. According to one aspect of the invention, a support system is provided with a device for applying electromagnetic forces to the vibrating object, and the compliant structure is used to support the electromagnetic device. The electromagnetic device is positively controlled as a function of (A) the position of the vibrating object and (B) the position of the electromagnet. The compliant structure may also be used to further attenuate high frequency vibration transmission. According to one aspect of the invention, the compliant structure permits some rocking and/or rotational motion of the electromagnet to simplify the vibration transmission mechanism. According to another aspect of the invention, the compliant structure operates as a slightly-damped stiff spring in the axial direction of the electromagnet.
