SMA Damped Tape Spring Hinge for Quasi-Static Deployment of a Satellite Solar Array
Abstract:
A tape spring hinge is one of the most typical deployment devices and is frequently used in miniaturized satellite due to its simplicity, lightweight, low cost and high deployment reliability. But a tape spring hinge mechanism has limited performance due to the performance trade-off between deployed stiffness and latch-up shock.In this study, to improve a conventional tape spring hinge mechanism, SMA damped tape spring hinge is proposed so that a satellite solar array can be quasi-statically deployed. The test result shows the feasibility of the proposed concept.
