ABSTRACT:
A device for absorbing the energy of vibration of one of two abutting members which has begun to vibrate due to forces applied to either of the two abutting members, so as to reduce the frequency and magnitude of vibration of one of the two abutting members. The primary energy absorbing element is a piece of elastomeric resilient material which contains a core (or cores) of a substantially incompressible, highly efficient dampening material; the presence or absence of this core of highly efficient dampening material will depend upon desired device stiffness and dampening characteristics. The primary energy absorbing element is surrounded by a flexible reinforced shell which contains and restrains said element, yet allows said element to deform in the transverse and vertical directions. Two end pieces or mounting plates are secured to opposite ends of the primary energy absorbing element.
