摘　　要：为了满足高档重型机床静压转台的高速性能,设计了一种双进油孔静压油腔结构。基于流体动力学理论,采用计算流体动力学(Computational Fluid Dynamics,CFD)数值模拟计算方法,研究了不同转速对静压油膜承载特性和由油膜剪切产生的温度场的影响。研究结果表明,新设计的油腔结构能满足静压转台高速回转的需求,改善了在高速情况下油膜出现的负压情况,该研究对静压转台的高速运转及油腔结构的优化有重要意义。To meet the high-speed performance requirements of hydrostatic turntables in high-end heavy-duty machine tools,a dual inlet oil hole hydrostatic oil chamber structure is designed.Based on the principles of fluid dynamics,Computational Fluid Dynamics(CFD)numerical simulation method is employed to investigate the influence of different rotational speeds on the load-carrying characteristics of the hydrostatic oil film and the temperature field generated by oil film shear.The results indicate that the newly designed oil chamber structure can fulfill the requirements for high-speed hydrostatic rotation and improve the occurrence of negative pressure in the oil film under high-speed conditions.This study is of significant importance for the high-speed operation and optimization of oil chamber structures in hydrostatic turntables.
