Abstract：

A　dynamics　model　of　a　spindle　system　for　capillary　compensated　multi-pad　hydrostatic　turntable　was　established.　The　dynamic　and　static　characteristics　of　partial　load　of　the　spindle　system　were　obtained　by　using　Simulink　software.　The　influences　of　different　external　loads　and　loading　positions　to　thickness　and　bearing　capacity　of　oil　film,　oil　cavity　pressure　and　the　deflection　angle　of　hydrostatic　turntable　were　analyzed.　A　delicate　test　rig　of　hydrostatic　turntable　was　constructed.　Dynamic　load　test　and　swept　sine　excitation　experiments　were　carried　out　for　hydrostatic　turntable　of　the　eight　oil　pads.　Numerical　results　and　experimental　results　show　that　the　theoretical　model　is　reasonable,　which　provides　a　theoretical　basis　for　optimizing　design　of　hydrostatic　turntable　and　improving　the　machining　precision　of　precision　machine　tools.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
