Abstract:
A dual-rate resilient isolator having a plurality of raised, generally conical bumps formed on an engagement surface thereof. The bumps in combination with a main body of the resilient isolator provide a dual-rate for isolating CRFM noise vibration and or other vibrations (via the relatively softer resiliency of the bumps) and isolating road vibration and shock (via the relatively harder resiliency of the main body) even though the bumps and the main body are composed of the same resilient material.
