Experimental 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 کاملMagnetic 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 کاملShape Memory Alloy Actuator forBio-medical application
In this paper various applications of shape memory alloys (SMA) in bio-medical field based upon their material properties are discussed, and a novel SMA spring actuator design for biopsy is proposed. Design parameters such as spring configuration, wire diameter required for designing the actuator were defined and obtained through experiments. Finally, itconcludeswith the possibility of using SM...
متن کاملA bidirectional shape memory alloy folding actuator
This paper presents a low-profile bidirectional folding actuator based on annealed shape memory alloy sheets applicable for mesoand microscale systems. Despite the advantages of shape memory alloys—high strain, silent operation, and mechanical simplicity—their application is often limited to unidirectional operation. We present a bidirectional folding actuator that produces two opposing 180 mot...
متن کاملDevelopment of a non-explosive release actuator using shape memory alloy wire.
We have developed a newly designed non-explosive release actuator that can replace currently used release devices. The release mechanism is based on a separation mechanism, which relies on segmented nuts and a shape memory alloy (SMA) wire trigger. A quite fast and simple trigger operation is made possible through the use of SMA wire. This actuator is designed to allow a high preload with low l...
