Abstract:An experiment device is designed,which is used to systematically analyze the material characteristics of Magnetically controlled Shape Memory Alloy(MSMA),and the relationship between flux density,temperature,stress,and strain is obtained.Based on the analysis results,a novel MSMA differential actuator is designed.The working principle is described,and the experimental results of the prototype are given.
