Vibration of a Shape Memory Alloy Wire

Experimental Study on Vibration Control of Shape Memory Alloy Actuated Flexible Beam

This paper describes the development of an experimental platform which analyzes and controls the vibration of a Shape Memory Alloy (SMA) actuated and piezo sensed flexible beam. The vibration is controlled using the interactive force of a pair of almost identical SMA wires connected in an antagonistic manner, arranged in parallel to and on both sides of the cantilever beam structure. Data acqui...

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...

Active position control of a shape memory alloy wire actuated composite beam

This paper presents the design and the experimental result of the active position control of a shape memory alloy (SMA) wire actuated composite beam. The composite beam has a honeycomb structure with SMA wires embedded in one of its face sheets for the active actuation. The potential applications of this experiment include thermo-distortion compensation for precision space structure, stern shap...

Nonlinear Position Control of a Flexible Beam Using Shape Memory Alloy Actuators

This paper presents a nonlinear control scheme for position control of a flexible beam system using Shape Memory Alloy (SMA) actuators. Due to their interesting properties such as force generation capacity, possibility of miniaturization, and power consumption, these devices have been gaining increased popularity in the past few years. However, SMA actuators possess undesirable characteristics ...
