Optimal Design of Shape Memory Alloy Wire Bundle Actuators

This research studied the optimal design of Shape Memory Alloy (SMA) muscle wire bundle actuators. Current literature describes the use of multiple muscle wires placed in parallel to increase the lifting capabilities of an SMA actuator, which however, is limited to wires of like-diameter. A constrained optimization problem was formulated, with constraints on the maximum number of wires, voltage...

Shakedown Response of Conditioned Shape Memory Alloy Wire

A series of experiments is presented examining the thermo-electro-mechanical response of commercially-available, conditioned, shape memory alloy (SMA) wires (Flexinol®, from Dynalloy, Corp.) during cyclic thermomechanical loading. A specialized experimental setup enables temperature control via a thermoelectric/heatsink in thermal contact with the wire specimen during various modes of testing. ...

Fuzzy Logic Position Control of a Shape Memory Alloy Wire

Assist. prof. dr. Daniela Maffiodo, prof. dr. Terenziano Raparelli, prof. dr. Guido Belforte; all: Dipartimento di Meccanica, Politecnico di Torino, Italy Abstract: Due to the complex thermomechanical characteristics of Shape Memory Alloy wires, it is important to develop control systems in order to design new applications for these smart materials. This paper presents three SMA wire position c...

Phase Transformation Temperatures for Shape Memory Alloy Wire

Phase transformation temperature is one of the most important parameters for the shape memory alloys (SMAs). The most popular method to determine these phase transformation temperatures is the Differential Scanning Calorimeter (DSC), but due to the limitation of the DSC testing itself, it made it difficult for the finished product which is not in the powder form. A novel method which uses the U...
