Abstract
-
This paper presents the design optimization procedure that was used to size the D-Struts™ used on the Passive/ Active Control of Space Structures (P ACOSS) program. While this design uses a diaphragm for the pumping member of the damper, the method can be adapted for other approaches. Fourteen D-Struts are fabricated and extensively characterized using the method of complex mechanical impedance. Performance agrees well with predictions, except that the peak phase lead is low. Additional compliance, which is responsibile for this loss in performance, is primarily due to the diaphragm flexing at its inner and outer edges. This paper suggests solutions to improve the diaphragm clamping as well as alternatives to using a diaphragm.
