摘要： 为更方便灵活的控制滑靴副的油膜特性,提出了一种以液压力和电磁力相平衡的磁性滑靴副结构,并建立了数学模型和有限元模型。分析了电压、电场强度等对磁性滑靴副工作性能与使用寿命的影响。结果表明：磁性滑靴副中铁芯与斜盘接触处电场强度最大,易出现放电影响使用寿命;主磁路能构成闭合回路且漏磁较少,励磁绕组线圈之间的磁场不存在叠加和干涉;安匝数越多电磁力越大,通入不同的电流磁感应强度峰值均出现在励磁绕组线圈顶端,磁感应强度达到峰值后迅速衰减并趋于平滑,在励磁绕组线圈底端时磁感应强度最小。

Abstract: In order to control the oil film for the slipper pair more conveniently and flexibly, the magnetic slipper pair is proposed which maintains balance by hydraulic pressure and electromagnetic force, and its mathematical model and finite element model are built. The impact of voltage, electric field strength etc. on magnetic slipper pair’s working performance and service life is analyzed. The results show that: the position of the swash plate in contact with the core of magnetic slipper pair has maximum electric field strength and prone to discharging electric which affect the service life. The main magnetic path forms a closed loop and has less leakage flux, there are no superposition and interference in each magnetic field distribution; The more ampere-turns, the larger electromagnetic force generates, when different currents are switched on, the magnetic strength’s peak appears in the place near the top of the pole coil. When the magnetic strength gets to its peak and decay rapidly, it then tends to be smooth. When it gets to the bottom of the excitation winging pole coil, the magnetic strength gets to its minimum.

Key words: magnetic slipper pair, electric field, electromagnetic force, ampere-turns, magnetic strength
