Paper Abstract

The enhanced isolation design demonstrates a damping enhanced high performance shock isolation mounts for marine rafted equipment. This design was specifically developed as to enable low-cost retrofit capability with damping enhanced high performance shock isolation performance. The approach started the C-Worthy isolator manufactured by Newport News Industries that represents an excellent performing shock isolation mount currently employed widely by the U.S. Navy on carriers, submarines, destroyers etc. The C-Worthy class of isolators are based upon Dupont thermoelastic materials. The retrofit procedure demonstrated that damping can be substantially increased for these mounts with only marginal impact on the shock isolation performance. The increased damping was added in a relatively inexpensive and retrofit fashion. This retrofit aspect is directly amenable to existing marine system installed mounts such as commonly used by the U.S. Navy. Testing procedures were employed to ensure that they meet Navy Milspec 17185A requirements.
