【摘要】：针对滑移的不同情况,将界面滑移分为无滑移、仅上边界滑移、仅下边界滑移和两边界均滑移4种类型,以力学平衡方程和Newton黏性流体力学公式为基础,基于楔形油膜模型,建立界面滑移状态下滑动轴承摩擦阻力计算模型,探究不同界面滑移时影响滑动轴承摩擦阻力的敏感参数,并借助有限元软件分析不同滑移情况下界面滑移对摩擦阻力的影响规律。结果表明:轴承的摩擦阻力主要由轴颈线速度、油膜滑移比、进出油口的压力、油膜厚度和承载力决定,油膜上、下表面均发生滑移时的摩擦阻力明显低于无滑移时的摩擦阻力。
[Abstract]:According to the different conditions of slip, the interface slip is divided into four types: no slip, only upper boundary slip, lower boundary slip and two boundary average slip. Based on the mechanical equilibrium equation and Newton's viscous hydrodynamic formula, the wedge oil film model is used. The friction resistance calculation model of sliding bearing under the condition of interface slip is established to explore the sensitive parameters that affect the friction resistance of sliding bearing with different interface slippage. The influence of interfacial slip on friction resistance is analyzed by means of finite element software. The results show that the friction resistance of the bearing is mainly determined by the journal speed, the oil film slip ratio, the pressure of the inlet and outlet, the thickness of the oil film and the bearing capacity. The friction resistance of the lower surface is obviously lower than that of the non-slip surface.
