Abstract:
The Dynamic Test Article (DTA) developed under the Passive and Active Control of Space Structures (PACOSS) program is a test-verified laboratory system for evaluating the behavior and interaction of passive and active control strategies on dynamically complex structures. The pneumatically suspended DTA possesses high modal density in the 1 to 10-Hz frequency range, with moderate levels of passive damping (near 5°k modal viscous) designed into the flexible modes. The system also includes a real-time control processor, ten reaction mass actuators, 23 velocity sensors, and a host workstation. Also, 200 accelerometers suitable for modal testing are available for identification and verification of performance. This presentation describes the DTA system components, capabilities, and overall test results. The DTA has been delivered to the Air Force Institute of Technology where it was assembled for use in further studies of controls/structures interaction and passive damping performance.
