Study on External Characteristics of Magnetically Controlled Shape Memory Alloy under Different Force

Magnetically controlled shape memory alloy (MSMA) can change its shape when it is exposed to a magnetic field, which provides a new way to produce linear motion and force. The MSMA material has another property yet: the MSMA material can change its magnetic property when it is subjected to mechanical force, which is known as inverse characteristics of MSMA. In this paper, a testing device which is used to testing external characteristics of MSMA material is presented. When the MSMA material is mechanically compressed by static force, a larger variation of magnetic flux density can be caused; a higher induced voltage is output under the action of impact force; the change laws of induced voltage peak-peak are studied under different input conditions (frequency, exciting force). The experimental results lay a foundation for MSMA sensor application.
