Development of a multi-link power drive made of a material with a shape memory effect

The shape memory effect is a phenomenon in which a plastically deformed metal restores its original shape as a result of heating. This effect is often used in engineering as actuators in various types of deformation devices, actuators, etc. In the proposed article, the designs of multi-link actuators made of a material with a shape memory effect are presented. As working elements of such power drives, it is proposed to use thermally thin elements made, for example, in the form of a wire made of TN-1 alloy. Particular attention is paid to the creation of structures from composite multi-link power elements that are connected in parallel and to the study of the effectiveness of the development of deformation forces developed by power drives from a material with a shape memory effect, and new design solutions. For the study, a specialized measuring stand was created that allows fixing several variables on a single time scale. Examples of the developed devices are illustrated with corresponding diagrams and photographs.
