In　this　paper,　the　nonlinear　oil-film　force　model　with　velocity　terms　of　a　hydrostatic　slide　turntable　system　is　established,　when　taking　no　account　of　the　minor　terms　of　the　Navier-Stokes　Equations　by　dimensional　analysis,　and　combining　with　the　bearing　capacity　of　an　oil-film　model　for　the　steady-flow　hydrostatic　slide　system　with　round　oil　chamber.　Consequently,　the　dynamic　equation　of　the　hydrostatic　slide　turntable　system　is　formulated.　In　addiction,　the　dynamic　properties　of　the　hydrostatic　slide　turntable　system,　subjected　to　different　variables,　are　investigated　by　virtue　of　numerical　simulation.　Thus,　the　research　results　presented　in　this　paper　will　provide　a　theoretical　basis　for　the　further　investigation　on　dynamic　properties　of　a　hydrostatic　oil-film　turntable　system.
