摘要

Magnetically controlled shape memory alloy (MSMA) is a new functional material, which can demonstrate not only a large strain and stress compared with other shape memory alloys but also a high energy density, fast frequency response and high precision of control compared with piezoelectric materials. Based on the magnetically controlled characteristic of MSMA, the constitution and operation principle of MSMA actuating device are presented. Experimental results show that MSMA not only has good magnetically controlled characteristic, but also MSMA actuating device is feasible. This study would lay a good foundation for MSMA's application in civil engineering.
