Three parameter, multi-axis isolators, isolation systems employing the same, and methods for producing the same

摘要

Embodiments of a three parameter, multi-axis isolator configured to limit the transmission of vibrations between a mass and a base are provided. In one embodiment, the three parameter, multi-axis isolator includes an isolator housing configured to be mounted to the base, opposing bellows sealingly mounted within the isolator housing, and a damper piston movably suspended within the isolator housing between the opposing bellows. The damper piston is configured to be coupled to the mass. The opposing bellows deflect with movement of the damper piston along multiple axes to limit the transmission of vibrations between the mass and the base.

1. A three parameter, multi-axis isolator for deployment between a mass and a base, the three parameter, multi-axis isolator comprising:
an isolator housing mountable to the base; opposing bellows sealingly disposed within the isolator housing; opposing hydraulic chambers defined, at least in part, by the opposing bellows and configured to be filled with a damping fluid; and a damper piston movably suspended within the isolator housing between the opposing bellows and configured to be coupled to the mass, the opposing bellows deflecting with movement of the damper piston along multiple axes to reduce the transmission of vibrations between the mass and the base; wherein, when the opposing hydraulic chambers are filled with the damping fluid, the damping piston displaces a damping fluid volume when moving in an axial direction by a first amount that is substantially equivalent to the damping fluid volume displaced by the damper piston when moving in a lateral direction by the first amount.
