铁镓合金电磁损耗分析
|
摘要
铁镓合金电磁损耗分析是高频铁镓合金导波激励装置、超声换能器以及振动主动控制结构的研究基础,因此分析铁镓合金在高频(磁场频率50 k Hz～400 k Hz)情况下的电磁损耗至关重要。采用AMH-1M-S型动态磁特性测试系统测量了环形铁镓合金在不同情况下的磁滞回线:相同磁场强度下不同交变励磁磁场频率、相同交变励磁磁场频率下不同磁感应强度、相同磁感应强度下不同交变励磁磁场频率。分别分析了上述情况下环形铁镓合金振幅磁导率变化规律以及介质储能和电磁损耗的变化情况。实验结果表明,在相同磁场强度为400 A/m时,励磁磁场频率由1 k Hz～200 k Hz,振幅磁导率下降了53.68%,电磁损耗增加了283倍;在相同励磁磁场频率100 k Hz时,磁感应强度由0.01 T～0.05 T,振幅磁导率增加了33.55%,介质储能与电磁损耗分别增加了18.13倍和25.97倍;在相同磁感应强度为0.05 T时,励磁磁场频率由50 k Hz～400 k Hz,振幅磁导率减小了39.73%,电磁损耗增加了16.9倍。此项研究为高频铁镓合金换能器设计与优化提供了实验数据基础。
The analysis of the electromagnetic losses in Fe-Ga alloy is the research foundation of Fe-Ga alloy guidedwave excitation devices at high frequency,ultrasonic transducers and active vibration control structures. Therefore,it is very important to analyze the electromagnetic losses of Fe-Ga alloys under high-frequency( magnetic field frequency from 50 k Hz to 400 k Hz). The hysteresis loops of ring-shaped Fe-Gaalloy under different conditions are measured by AMH-1 M-S dynamic magnetic characteristic test system,which are different alternating excitation field frequencies under the same magnetic field strength,different magnetic induction intensity under the same alternating excitation field frequency and different alternating excitation field frequencies under the same magnetic induction intensity. The variation laws of the amplitude permeability,the changes of dielectric energy storage and electromagnetic loss of the ringshaped Fe-Ga alloy in the above-mentioned situation are analyzed using the testing data. The results show that amplitude of magnetic permeability decreases by 53.68% and electromagnetic loss increases by 283 times when the same magnetic field is 400 A/m and the magnetic field frequency is from 1 k Hz to 200 k Hz. Amplitude of magnetic permeability increases by 33.55%. Energy storage medium and electromagnetic loss increase by 18.13 times and 25.97 times respectively when the magnetic field frequency is 100 k Hz and magnetic density is from 0.01 T to 0.05 T. Amplitude of magnetic permeability reduces by 39.73% and electromagnetic loss increases by 16.9 times when the same magnetic density is 0.05 T and magnetic field frequency is from 50 k Hz to 400 k Hz. This study provides an experimental data basis for the design and optimization of high frequency Fe-Ga alloy transducers.
