In　this　paper,　a　nonlinear　oil-film　force　model　with　velocity　term　for　hydrostatic　slide　system　with　rectangular,　sector　and　round　chamber　is　established　respectively,　by　eliminating　the　small　amount　after　the　dimensional　analysis　with　the　help　of　Navier-Stokes　equation,　and　combining　with　the　oil-film　bearing　model　of　Hydrostatic　Slide　System　of　constant　oil　supply.　And　the　turntable　dynamic　equations　of　hydrostatic　slide　system　with　different　chambers　are　formulated　consequently.　Furthermore,　the　analysis　of　dynamics　properties　of　the　hydrostatic　slide　turntable　with　the　same　oil　chamber　area　is　investigated　by　numerical　simulation.　This　research　provide　theoretical　bases　of　the　further　studying　and　improving　of　the　rest　aspects　property　of　hydrostatic　oil　film-turntable　system.　©　2011　IEEE.
