英文摘要： The collection of environmental vibration energy to supply power of the electronic equipment has aroused the concern of science and technology researchers. However, so far, the research on collecting vibration energy with using magnetically controlled shape memory alloy (MSMA) has not yet been reported. Based on the previous research of MSMA in magnetically controlled characteristics, energy conversion, as well as actuators and sensors supported by National Natural Science Foundation, this project will propose a design concept using MSMA to collect vibrational energy to generate electric power. The conversion properties and mathematical relationships between mechanical force, magnetic field and vibration frequency in MSMA will be discussed, and the energy collection and storage circuit, oscillator circuit, power management circuit and the control system will be simulated. Furthermore, the mechanism, structure and control strategy of the new generator system will be studied. On the basis of experimental studies, an integrated design and analysis platform will be built to simulate vibration energy production, collection, storage and management of the MSMA vibration energy collection and generator system. The mathematical model and control method of an MSMA intelligent micro power system will be studied. Finally, a
