Test system of external properties in magnetically controlled shape memory alloy of using labview

The Magnetically Controlled Shape Memory Alloy (MSMA) is a new functional material which is found in recent years. MSMA has characteristics of large deformation rate and high response frequency in the martensite state. It is an important potential material for the next generation of intelligent actuators and sensors. This paper takes Labview virtual instrument as the core of external properties test system to improve the traditional test system shortcomings such as slow response, low accuracy, less test points. Also it provides an excellent experimental platform and reference value for further study of MSMA characteristics test system.
