ABSTRACT
Mounts are vibration isolators used to connect two objects and isolate vibrations from one to the other. Many types of mounts, from passive to active, have been developed to be used in various applications such as vehicles, optical devices, and high-precision machines. Rubber mount is one of the most commonly used passive mounts. It can be effectively used to isolate vibrations at high frequencies, but the isolation performance at resonant frequencies is low because of its low damping property. The passive hydraulic mount has been developed to meet large damping requirement, but at nonresonant and high frequencies, its isolation performance is worse than that of the rubber mount. Therefore, passive mounts are not suitable for vibration-sensitive devices that need high-performance isolation under wide frequency range disturbance environments such as navy shipboard equipment.
