Abstract

This paper describes design, analysis, and test experience on a large amplitude, tridirectional, distributed suspension system for testing large flexible space structures in a simulated weightless environment. Three cables are attached to the test article at each attachment point, as opposed to one vertical cable in a unidirectional system. Horizontal as well as vertical isolation are thereby achieved without requiring a large overhead clearance. Rotary actuators are employed to utilize overhead space efficiently. Position and torque-controlled motors are used in combination with torsional springs to achieve a large amplitude, high frequency isolation capability.
