Abstract
-
A viscous-damping technique offering high damping for spacecraft truss structures has been under development since 1986. The technique, known as the D-Strut™, uses a small mechanical viscous damper configured in an inner-outer tube-strut configuration, and replaces the nominal-type strut. The viscous-damped D-Strut has been employed in more compliant isolation systems for space applications, including the Hubble Space Telescope. The United States Air Force and Jet Propulsion Laboratory have investigated D-Struts for use in high specific-stiffness truss structures. This technique is an attractive means of attaining significant damping levels in space structures.
