Abstract

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.
