Abstract: A vibration isolator includes a series of hard bushings that press against each other and slide, under the constraint of friction from the engagement of the bushings. A fastener, such as a bolt, passes through the engaged bushings, and one or more springs provide a spring force that maintains the engagement of the bushings. The bushings may include top and bottom bushings having chamfered surfaces, which engage corresponding upper and lower sloped surface on a middle friction bushing which can slide relative to the top and bottom bushings. The isolator may be part of a vibration isolation system that includes multiple isolators to provide isolation for an isolated object. The bushings may be made of metal or another suitable hard material. The isolator may be suitable in particular for vibration isolation in situations where vibrations are of severe, but short duration.
