Oil film analysis of swash plate/slipper pair based on CFD

  • 摘要: 结合三维Navier-Stokes方程和任意拉格朗日-欧拉(ALE)描述方法,首先,提出了一种基于计算流体力学(CFD)的滑靴副油膜特性分析方法,该方法能综合考虑滑靴副结构参数、柱塞泵工况参数对油膜特性的影响。然后,针对某种滑靴副结构,仿真得到了24种不同工况下的油膜厚度,分析了工况(温度、转速和出口压力)与滑靴副油膜的定量关系。本文还提出了一个与油膜特性相关的液动力参数的描述公式,并基于某固定结构尺寸的滑靴副CFD仿真结果,研究证明了对于固定结构的滑靴副结构,该参数仅与油液黏度(温度)相关,与其他工况参数无关。根据液动力参数公式,可以方便地给出滑靴副油膜厚度的解析方法。最后,将基于解析方法与基于CFD仿真方法得到的油膜厚度结果进行了对比,证明了解析方法的准确性。
