Theoretical and experimental study of the dynamic transient characteristics of a hydrostatic bearing

The transient characteristics of a hydrostatic bearing under a step load have been studied by considering the compressibility of oil (containing air bubbles). The characteristic equations of the bearing during the transient stage have been set up, the duration of the transient stage has been obtained and the effects of the main parameters of the bearing system on the transient characteristics have been analysed. This study provides a new theoretical basis for improving the dynamic support precision of high quality bearings.
