Magnetic Shape Memory alloy based Fiber Bragg Grating magnetic field sensor

With shape memory function of new smart material, the magnetic control properties of magnetic shape memory alloy could be used to fabricate intelligent actuators for vibration control of structures. In order to study its magnetic properties, this text selected Ni53Mn25Ga22 as the material for the research and development of actuator drive, And two MSMA test specimens were prepared for the experimental study under the coupled action of the temperature, preload pressure and magnetic field. The results showed that the strain of MSMA induced by magnetic field decreased with the increase of the preload pressure at constant magnetic field. The deformation performance was best when the magnetic induction intensity was about 0.5T. And the constitutive relations were fitted for the actuator production to lay the foundation for later.

Magnetic Shape Memory Alloy

In this paper, a kind of Magnetic Shape Memory Alloy (MSMA) model based on hysteretic nonlinear theory was developed. Von del Pol nonlinear difference item was introduced to interpret the hysteresis phenomenon of strain-magnetic field intensity (MFI) curve of MSMA. The final relationship among strain, stress and magnetic field intensity was obtained in partial least-square regression method to describe the variation of strain-MFI curve with stress. The result of forecast test shows that the model can describe the characteristics of MSMA in different stress well. The new MSMA model is easy to be analyzed in theory, which is helpful to application of MSMA in engineering fields.
