摘　　要：随着电子工业的不断发展,各个产业对于无线电子设备的需求愈发迫切,很多研究团队正在探讨利用环境能量进行供电的可行性。振动换能器将振动能量转换为电能并加以储存,将储存的电能应用于无线传感器等微电子设备的供电,可以使相应传感器脱离电源线和有限的电池能源的束缚。基于磁控形状记忆合金(Magnetically Controlled Shape Memory,MSMA)的逆效应提出了一种悬臂梁式MSMA振动换能器,阐述了振动换能器的工作原理和基本结构,提出一种新型换能器磁路结构,并利用ANSYS Maxwell仿真软件,对磁路进行了分析。建立了系统的数学模型,对相关参数进行灰箱测定,完成了对换能效率的理论分析。制作了MSMA振动换能器的试验样机,实验结果验证了该系统的可行性和有效性。With the continuous development of the electronics industry,the demand for wireless electronic equipment in various industries is becoming more and more urgent.Many research teams are exploring the feasibility of using environmental energy for power supply.Vibration transducers convert vibration energy into electrical energy and store it.Applying the stored electrical energy to the power supply for microelectronic devices such as wireless sensors can free the corresponding sensors from the shackles of power cords and limited battery energy.Based on the inverse effect of Magnetically Controlled Shape Memory(MSMA),a cantilever beam-type MSMA vibration transducer is proposed.The working principle and basic structure of the vibration transducer are explained,and a new type of transducer is proposed.The magnetic circuit structure of the device is analyzed using ANSYS Maxwell simulation software.The mathematical model of the system is established,the relevant parameters are measured in a gray box,and the theoretical analysis of the efficiency of the energy conversion is completed.
