VERTICAL LIQUID INERTIA VIBRATION ISOLATOR

摘要

A vibration isolator for connecting a first body and a second body, comprising a housing having an inner surface defining a fluid volume; a tuning fluid disposed in the fluid volume; an inner cylinder disposed in the fluid volume and having a surface disposed to substantially segregate a portion of the fluid volume, the segregated portion defining a first chamber within the fluid volume; a second chamber having a variable volume; a passage connecting the first chamber to the second chamber and permitting fluid flow from the first chamber to the second chamber wherein the first and second chambers and the passage define a fluid reservoir; a bearing arranged to connect the vibration isolator to the first body; and a gas-to-fluid accumulator having fluid communication with the uppermost portion of the fluid reservoir.
