Abstract:

	 Systems will be required to isolate the experimental payloads from inherent Space
Station vibrations. The vibration requirements can best be met by active isolation
systems that have the capability to adjust to differing vibration environments, changes
in payloads, and changes in desired isolator dynamics. Magnetic suspensions are an
extremely promising approach to implementing these active isolation  systems. Their
desirable characteristics include high band-width, linearity, stability, high efficiency,
multi-axis capability, and ease of integration with electronic control systems.
	Phase I of this research program developed typical vibration isolation requirements
for Space Station. A magnetic suspension system capable of meeting these requirements
was then designed. This design features six-degree-of-freedom actuation in a single
compact unit.

Potential Commercial Application:

Potential Commercial Application: Vibration isolation systems may be used in commercial
applications as well as in Space Station, e.g., precision pointing and tracking systems,
inertial instrument test tables, crystal growth, and optical benches.
