Abstract :
Pressure distribution of heavy type hydrostatic center rest used in the heavy CNC equipment is hard to be measured directly because the oil film is very thin in the practical engineering. In order to solve this problem, a simulation research concerning the pressure field of hydrostatic center rest is described. The Finite Volume Method is used to compute the three-dimensional pressure field of gap fluid between the work piece and hydrostatic center rest according to computational fluid dynamics and lubricating theory. The pressure distribution law is revealed and the theoretical basis is provided for the optimal design of hydrostatic center rest.
