Passive Vibration Isolation
Eugene I. Rivin, Wayne State University

A comprehensive review of principles of passive vibration isolation will be presented for vibration isolation of precision and other vibration sensitive objects. Generalized inertia and geometric parameters of real life object and basic characteristics of elastic mounts will be formulated. Important issues related to single-, two-, and three-degrees-of-freedom will be addressed, especially coupling in 3 DoF systems and its reduction. A non-traditional approach to deriving principles and criteria of vibration isolation (proven by numerous applications) will be presented showing that a resonance in the isolation system is a normal working regime, thus establishing importance of damping enhancement for good vibration isolation. Realization of the required elasticity in vibration isolators as well as optimized designs of isolators will be addressed. A special attention will be given to designs of nonlinear "Constant Natural Frequency" isolators whose characteristics have proven to be superior for isolation of vibration sensitive objects.
