Simulation of Shape Memory Alloy (SMA)-Bias Spring Actuation for Self-Shaping Architecture: Investigation of Parametric Sensitivity

Application of Shape Memory Alloy (sma) Based Actuation for Refreshable Display of Braille

Persons with blindness access computers with the help of refreshable Braille displays and speech synthesis softwares. Braille has distinguished advantages over synthetic speech, especially because of its important role in uplifting education, employment and income. However, commercially available Braille displays are typically priced in the range of 2500-4000 USD (65-100 USD per Braille charact...

Ex Perimental Verification of the Shape Memory Alloy (sma) Spring Actuator for Application on In-pipe Machine

M. Kelemen, I. Virgala, E. Prada, T. Lipták Faculty of Mechanical Engineering, Technical University of Košice, Slovakia Th e paper deals with Shape memory alloy (SMA) spring analysis and its possibility for usage as actuator for in-pipe machine. In the paper the inner structure of SMA is introduced. Further, the experimental analysis of SMA contractor and expander was done. From the experiments...

SEISMIC OPTIMIZATION OF STEEL SHEAR WALL USING SHAPE MEMORY ALLOY

Nowadays, steel shear walls are used as efficient lateral-load-resistant systems due to their high lateral stiffness and carrying capacity. In this paper, the effect of substituting a shape memory alloy (SMA) material is investigated instead of using conventional steel in the shear wall. A numerical study is conducted using finite element method (FEM) by OpenSees software. For this purpose, at ...

Shape Memory Alloy (sma) Coil Actuators for Use in Controllable Mechanical Counter-pressure (mcp) Space Suits

Mechanical counter-pressure (MCP) space suits, which apply pressure to the wearer using tight-fitting materials rather than pressurized gas, offer numerous mobility and mass advantages over traditional gas-pressurized suits [1]. However, MCP design challenges related to pressure uniformity, pressure magnitude, and donning/doffing remain unsolved [2]. Previous MCP efforts have focused on passive...
