Shape memory alloy (SMA) has attractive characteristics such as shape memory effect, super elasticity and hysteresis of stress-strain relationship. By utilizing SMA for actuators of large deployable panels, it is expected to realize controlled and low-shock deployment, sequential deployment, shape control during deployment, also shape control and vibration absorption after deployment, and so on. Generally, expected functions of actuators for deployment, shape control, and vibration suppression for panel-like huge space structures are small attitude deviation during deployment, low shock at latching, good structural accuracy, controllability of static shape such as thermal deformation compensation, large vibration damping, capability of folding panels with a certain quantity of thickness. A multi-functional actuator utilizing SMA may be able to satisfy the requirements. In this paper, proposed is a conceptual design of a multi-functional SMA actuator, which is applicable to a unified panel of power generation and transmission of a solar power satellite. The basic principles and possibilities of deployment, latch mechanism, shape control and vibration absorption are presented. A hinge for two-way angle control effect can be realized by making a pair of SMA coils, each of which undergoes one-way shape memory treatment at different aperture angle. One of the pair of SMA coils is conducted to heat up to the reverse transformation temperature in order to activate the shape recovery effect one way. In the case that both of the pair of SMA coils are conducted at the same time to heat up, the hysteresis loop of stress-strain relationship at the high temperature phase of SMA can be used to damp the vibration of a large amplitude. The hinge with two-way shape memory effect requires a latching mechanism that can latch and release at any hinge angle between the two panel units. The latch can be designed by combining permanent magnet and electromagnet, and a tongue of magnetic material. Demonstration model of the function has also been made. Instead of thick panel unit with actual thickness, a thin rigid panel represents the mid-surface of the thick panel unit. Spacers with height of half of the thickness of a thick panel unit are attached to the both sides of the mid-surface panel in order to demonstrate the thick panel unit. The SMA hinges and magnetic latches combine 8 x 4 panel units. Some functions of the multi-functional hinge of the panel have been proved. |
