Bibliography
Provides two methods for determining the dynamic transfer stiffness for translations of resilient elements other than resilient supports. Examples are resilient bellows, shaft couplings, power supply cables, hoses and pipe hangers. Elements filled with liquids, such as oil or water, are excluded. Applies to resilient elements with flat flanges or flat clamp interfaces.
