Simulating and Optimizing Temperature Field of Oil Film for CNC Vertical Lathe Hydrostatic Rotary Table

  • 摘要: 主要针对数控立车液体静压转台油膜发热控制难题,采用CFD(computational fluid dynamics)仿真软件Fluent数值模拟油膜温度场分布。讨论了转速及黏度对油膜温度场的影响,得到油膜温升最大点主要集中在沿径向封油边外侧。利用MATLAB对其黏度因素进行优化得到最小功耗下的油膜黏度,得到在黏度为0.061 7 Pa·s时,可使静压系统功耗最低,同时油膜温升也小的预测结论。仿真结果为工程实际油膜温度控制提供了理论依据。
