Description
Summary:Transformable large-sized space structures are delivered to orbits in a folded transport state. So, their further transformation into working position is associated with the implementation of the deployment process. The opening procedure of the transformable structure occurs under the force of actuators. These actuators usually are: compressed or stretched springs, electric motors, active elements made of materials with shape memory effect. The issues of modelling and dynamics of such systems attract considerable interest of scientists, engineers and designers. During the transformation of the structure, dynamic loads arise on the elements of the system, which are of a shock nature. To eliminate dynamic shock loads, it is proposed to use actuators made of shape memory material. Modelling and experimental studies of an actuator made of titanium–nickel alloy have confirmed the possibility of its use for transformable space structures.
