International Classification:

F16M 13/00

US Classification:

248562, 248638, 343878

Abstract:

A vibration isolation system () for a payload (). The vibration isolation system provides a level of vibration isolation for all vibration translational and rotational components, while minimizing the moment of the payload mass relative to the isolation system. The system includes a base () and a plurality of vibration isolators (). Each vibration isolator includes a semi-rigid first support member () having first portion () positioned below the base and an opposing second portion () positioned above the base, and a second support member () having a first portion () fixed to the base and an opposing second portion () extending above the base. An elastomeric coupling () couples the first support member to the second support member at a height that is approximately equal to a height of a center of gravity () of a combined mass of the base and the payload above the base.

Abstract:

Twist control system and method for controlling twisting distortion in a beam caused by temperature changes. In a beam having an inherent amount of temperature induced twisting a wrap can be helically bonded to the beam. The wrap has a wrap material type, a wrap cross-sectional profile, and a wrap angle that can be selectively chosen for providing a desired twist control of the beam. The twist control applies a twisting force to the beam which is approximately proportional to the temperature change. The twist control can be used to eliminate the thermally induced twist associated with a particular beam or for providing a desired amount of twist.
