摘要

摘要: 运用界面滑移可在两平行平板表面间形成具有承载能力的流体动压膜．在流体入口区，静止平板表面上流体-接触表面的界面剪切强度具有较低值，以在该界面处产生界面滑移，而在流体出口区，静止平板表面上流体-接触表面的界面剪切强度具有足够高的值，以避免在该界面处出现界面滑移．整个运动平板表面上流体-接触表面的界面剪切强度具有足够高的值，以避免在运动平板表面上出现界面滑移．分析表明，这种流体动压接触区具有显著承载能力．使整个接触区具有最大承载能力的流体出口区宽度与入口区宽度的比值为0.5．

Abstract: Boundary slippage was used to generate the load-carrying capacity of the hydrodynamic contact between two parallel plane surfaces. In the fluid inlet zone the fluid-contact interfacial shear strength on the stationary surface is set as low to generate boundary slippage there, while in the fluid outlet zone the fluid-contact interfacial shear strength on the stationary surface is set as high enough to prevent the boundary slippage occurrence there. The fluid-contact interfacial shear strength on the whole moving surface is set as high enough to prevent boundary slippage on the moving surface. These hydrodynamic contact configurations are analyzed to generate the pronounced load-carrying capacity. The optimum ratio of the outlet zone width to the inlet zone width for the maximum loadcarrying capacity of the whole contact is analyzed to be 0.5.
