磁流变液的电学特性可以广泛应用于自动控制、医疗、汽车工业、飞机制造等诸多领域。推导出了磁流变电容与介电常数之间的计算公式,制作了可以盛载磁流变液的可变电容,测量了磁流变液作为电解质时电容随磁场的变化情况,以及不同浓度的磁流变液的介电常数随磁场的变化情况,得到了磁流变液电容-磁场变化的曲线和磁流变液介电常数-磁场变化的曲线,最后对实验结果作了分析,得出当磁场增大时,介电常数也变大,从而导致磁流变电容增大的结论。
The electrical characteristics of magnetorheological fluid can be widely used in automatic control,medical,automotive,aircraft manufacturing and many other areas. This article have derived the formula of MRF between capacitance and dielectric constant,made the capacitors which can load the MRF.And then we measure the change of capacitance when the MRF is seen as a kind of electrolyte during the time of magnetic field change.And we also measure the sensitivity of the dielectric constant of different concentrations of MRF as the magnetic field changes.And at last,we have made the curve of the capacitance-magnetic induction intensity,capacitance-concentration and then the experimental results have been analyzed.We have the conclusion that when the magnetic field increases,the dielectric constant is also larger,resulting in increased capacitance of the conclusions of MRF.
