Desenvolvimento de um sistema para caracterização de atuadores de liga com memória de forma

Abstract

Alloys that have the shape memory effect play a significant role in current studies, due to the fact that this type of phenomenon increases the range of possible applications. This shape memory effect is the material’s ability to return to a previous state from a stimulus. This work uses the NiTi alloy wire as a study object and aims to develop a test bench that makes it possible to monitor and characterize a wire of this material. This bench is personalized and previously instrumented. Therefore, the work presents this bench together with all the components that allow the analysis of the shape memory effect,and also shows graphs describing the behavior and training of the wire.
