摘要

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。

Abstract: In order to control the heating of the oil film of a CNC vertical lathe hydrostatic rotary table, we use the CFD (computational fluid dynamics) software Fluent to simulate the temperature field of the oil film and then discuss the temperature distribution regularity at its different rotational speed and viscosity. The simulation results and their analysis show that the high-temperature zone mainly concentrates on the outside edge of radial seal oil. Assuming the power consumption is minimal, we obtain the viscosity of the oil film with MATLAB to optimize its viscosity factor. When the viscosity was 0.061 7 Pa·s, the vertical lathe hydrostatic rotary table has the minimum total power consumption, and its oil film temperature is also low.
