摘　　要：采用智能材料磁控形状记忆合金(MSMA)将机械振动能量转换成电能为无线电子设备供电已备受关注。该文利用MSMA的维拉利效应(逆磁致伸缩效应)分析了MSMA振动能量采集器工作原理,计算并确定了振动能量采集系统的磁轭、线圈、保护系统、固定装置的尺寸和性能参数。利用ANSYS软件对系统进行了仿真,验证了各部分结构参数和材料选型的正确性。在此基础上,设计制作了MSMA振动能量采集器样机,搭建了MSMA振动能量采集器实验平台,进行了振动力激振实验,得到了在不同输入频率和应力大小条件下感应电压的输出曲线,实验和仿真结果表明,利用MSMA材料可将机械振动能量转化为电能,为振动能量收集利用提供了参考依据。Using magnetic shape memory alloys（MSMA）smart materials to convert mechanical vibrational energy into electrical energy so as to power wireless electronic devices has been widespread concerned by many scientific and technological workers.This paper has analyzed the working principle of the MSMA vibration energy harvester,calculated and identified the magnetic yokes,coils,protection system,dimensions of the fixtures and performance parameters of vibration energy harvesting system by utilizing the Villari effect（inverse magnetostrictive effect）of the magnetic shape memory alloy.In addition,this paper has simulated the system using ANSYS 13.0software and verified the correctness of the structure parameters of each part and material selection.On this basis,we have designed the MSMA vibration energy harvester prototype,built MSMA vibration energy harvester experimental platform,conducted vibration force excitation experiments and obtained the output curve of induced voltage under the conditions of different input frequency and different stress.Finally the experimental and simulation results have demonstrated the feasibility of converting mechanical vibration energy by MSMA material into electrical energy and provided a reference for further vibration energy harvesting.
