Abstract

Shape memory alloys are a group of intelligent materials, which due to their unique characteristics have various applications in different industries such as aerospace, robotics, medical sciences and so on. Nowadays, improving the performance of air vehicles has received much attention from researchers. Wing form change during flight due to the air pressure is a very important issue in this field. Excitation mechanisms can be used to change the wing form during flight. Therefore, the wing can perform optimally in-flight conditions. Shape memory alloy actuators are very useful in excitation mechanisms because of their low weight and appropriate thermomechanical properties. In this study, the details of a mechanism in which shape memory alloy springs are used as torsion actuators to provide the wing twisting around the axis of the vehicle’s body, are designed and presented. For this purpose, first the behavior of shape memory alloys has been studied. Then, by examining the constitutive equations of these materials, a model for the shape memory alloy springs is presented. Next, by implementing this model in MATLAB software, the shape memory alloy spring’s behavior is analyzed in the proposed mechanism. Then, by using the results of this implementation, the components used in the mechanism are designed geometrically and the safety factor of each component is calculated.
