Vibration Isolation Materials

Abstract

The definition of vibration isolation is the separation, or isolation, of the vibratory forces or motion of one object from another. This is generally accomplished by inserting a flexible material between the driving object and the driven object. Such materials, if sufficiently flexible, will transmit little of the vibrational forces to the driven object. Vibration isolators with little damping are capable of extreme reduction of vibration transmission at the higher frequencies but they permit a great transmission of vibration at the resonant frequency of the system. The addition of damping will limit the response at the resonant frequency but may also reduce the isolation capability at the higher frequencies.
