Magnetic Shape Memory Alloy and Actuator Design
In the field of micromechatronics, microrobotics and specially microfactories, active materials are used in most cases. They permit high resolution and distributed actuation. In this area, Magnetic Shape Memory Alloys (MSMA) are possible candidates. If a lot of studies deal with MSMA, only few applications use them until now. MSMA are attractive active materials because they have large strain (...
متن کاملExperimental Hysteresis Identification and Micro-position Control of a Shape-Memory-Alloy Rod Actuator
In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind. The current study aims at developing a micro-position control system ...
متن کاملOptimal Design of a Shape Memory Alloy Actuator for Microgrippers
In this paper, a modular microactuator based on shape memory alloy (SMA) actuation to drive the joints of a microgripper is described. Its design is a combination of two SMA actuators installed on the links of a special mechanism : one of them drives the rotation of the joint and the other one produces the necessary force to manipulate objects. An accurate model of the thermo-mechanical behavio...
متن کاملShape Memory Alloy Actuator Controller Design for Tactile Displays
This paper describes the design of a controller for a tactile shape display for dexterous telemanipulation applications. This device consists of an array of pin elements which rest against the human finger tip. Shape memory alloy (SMA) wire actuators raise individual pins to approximate the desired surface shape on the skin. To overcome the slow response times of SMA actuators we have implement...
متن کاملBehavioral Model and Experimental Validation for a Spool-Packaged Shape Memory Alloy Actuator
Shape memory alloy (SMA) based actuators have the potential to be lower mass, more compact, and more simplistic than conventional based actuators (electrical, hydraulic, etc); however, one of the key issues that plagues their broad use is packaging since long lengths of wire are often necessary to achieve reasonable actuation strokes. Spooling the wire around pulleys or mandrels is one approach...
