摘　　要：采用FLUENT软件对重型恒流静压轴承油膜的三维压力分布及流场分布进行了数值分析,重点分析进出口区域的流速,并研究了出口压力与流速变化趋势。分析结果表明,流场进口附近流速变化剧烈,但是整体流动呈现很强的规律性。油膜整体压力场成均匀对称分布,不受出口位置影响。为进一步研究重型静压轴承的性能与设计提供理论依据。A three-dimensional simulation was performed numerically for pressure distribution and flow distribution of heavy hydrostatic bearing under the condition of constant flow using FLUENT software.Key study was focus on the flow rate of inlet and outlet regions.The change trends of pressure and flow rate of outlet area were also studied.Results show that flow rates change rapidly in the vicinity of inlet region,but the flow field presents a clear flow pattern generally.The whole pressure field of oil film presents a uniform and symmetrical distribution regardless the impact of region.These results would provide some constructive instructions for the performance and design of heavy hydrostatic bearing.
