Numerically Simulating Pressure Field of Oil Film in a New Hybrid Rotary Table

  • 摘要: 以新型螺旋油楔动静压转台为研究对象,采用基于Navier-Stokes方程的CFD(Computational fluid dynamics)软件模拟转台内部润滑油的压力场分布,分析不同转速和油膜厚度对转台内部压力场分布的影响,并进行了实验验证。分析结果表明,在同一供油压力下,油膜厚度较转速对静压油膜压力的影响更为明显;而油膜厚度和转速都会对动压压力峰值造成显著影响;油膜厚度一定且转速较高时,动压压力峰值明显高于静压腔内压力。CFD仿真结果与实验测试结果基本吻合,从而证实了仿真结果的可靠性及分析方法的可行性。
