| 摘 要： | 基于水-固两相单流体模型,研究润滑过程中的固体颗粒对低黏度润滑介质的影响。以无限宽楔形滑块为计算模型,推导出特定假设条件下考虑惯性力和界面滑移的低黏度介质润滑的雷诺方程,并通过不同条件下雷诺方程的求解,探讨固体颗粒含量对低黏度介质润滑特性的影响。结果表明:在对低黏度介质润滑特性进行研究时,需考虑其惯性力和界面滑移影响;固体颗粒的存在一定程度上增大润滑膜的压力和承载能力,颗粒含量越大,承载能力越大,但颗粒含量对润滑膜整体的压力分布状态几乎不会产生影响;惯性力增大固体颗粒对润滑介质的影响程度,而界面滑移减小固体颗粒对润滑介质承载能力的影响,发生滑移时,颗粒基本不影响润滑膜的承载能力。
