摘要 为了探究铁镓合金在不同磁场频率下产生应变和输出能量的变化规律,设计了一种双励磁线圈结构的铁镓换能器,研究了铁镓合金换能器的静态和动态输出特性。基于有限元法计算了铁镓合金换能器上棒状铁镓合金在不同频率下的磁场分布情况。利用磁能与机械能的转换关系,分析了铁镓合金换能器在不同磁场频率下的电磁损耗、磁能存储和输出机械能变化规律。结果表明,随着磁场强度的增加,铁镓合金换能器的静态输出应变和输出位移先线性增大之后趋于饱和。铁镓合金换能器静态输出的最大应变为80×10-6,输出的最大位移为3×10-6 m。棒状铁镓合金的最顶端和最底端的磁场强度较大,且随着磁场频率的增加而降低;棒状铁镓合金的中间部分磁场强度较小但分布均匀,且随着磁场频率增加而增加。铁镓合金换能器的动态输出位移曲线为蝶形曲线,在磁场频率为50 Hz时,铁镓合金换能器输出的机械能最大为69.598 J/m3

Abstract:In order to investigate the variation law of strain and output energy of Fe-Ga alloy at different magnetic field frequencies, the double-pole coil Fe-Ga alloy transducer was designed and the static and dynamic output characteristics of the Fe-Ga alloy transducer were studied. Based on the finite element method, the magnetic field distribution of the Fe-Ga rod alloy on the transducer was calculated at different frequencies. The change of electromagnetic energy, magnetic energy storage and output mechanical energy of the Fe-Ga alloy transducer at different magnetic field frequencies is analyzed using the conversion relationship between magnetic energy and mechanical energy. The results show that with the increase of magnetic field, the static output strain and the output displacement of Fe-Ga alloy transducer firstly increase linearly and then tend to saturation. The maximum strain of the static output of Fe-Ga alloy transducer is 80×10-6, the maximum output displacement is 3×10-6 m. The magnetic field of the top and bottom ends of Fe-Ga rod alloy is larger and decreases with the increasing of frequency. The magnetic field of the middle part of Fe-Ga rod alloy is smaller but evenly distributed and increases with the increasing of frequency. The dynamic displacement curves of Fe-Ga alloy transducer are butterfly curves. When the frequency is 50 Hz, the mechanical energy of the Fe-Ga alloy transducer is maximum 69.598 J/m3.
