Abstract
The effects of hold down device on the slipper's dynamic film was presented. Considering slipper's tilt and pressure-elasticity effect of slipper's lubrication surface, introducing the interaction between slipper and different hold-down device and according to the external forces and moments on slipper, the dynamic equations to describe micro-movement of slipper were established. Variation laws of the slipper's film thickness within a complete rotating period of the barrel were obtained by solving the kinetic equation and lubrication governing equation simultaneously. The different hold-down device's effect on slipper's dynamic characteristics was discussed. The results show that oil-film thickness decreases if the hold down device with central spring is used to alleviate the slipper's tilt. Hold down device with fixed clearance doesn't influence the oil-film's thickness during the delivery region and slipper's minimum film can be increased at suction region. Therefore the effect to alleviate the slipper's tilt is remarkable.
