ABSTRACT:
An apparatus and method for selecting an appropriate viscous fluid for use in control moment gyroscopes, reaction wheels, momentum wheels and the like. Components such as the housing, the rotor, and the viscous fluid are modeled using a three-parameter isolator system, which allows optimization of the damping action for a given application.
