Thermo magneto mechanical model and simulation of vibration generator of magnetically controlled shape memory alloy

Based on the law of electromagnetic induction, by analyzing the MSMA martensitic variants and its magnetic field properties this paper deduced the vibration generator heat magnetics mathematical model with the characteristics of Magnetically Controlled Shape Memory Alloy (MSMA), such as large deformation rate, easy to control, large output of reversible effects of induced voltage. Based on the mathematical model, this paper gets the Variation of the induced voltage that under the the action of the magnetic field and the applied stress. Finally, the model was tested in MATLAB simulation environment. Simulation results verify the feasibility of the use of MSMA for power generation and the correctness of mathematical models.
