中文摘要：

根据高速重载工况下收敛楔中流体润滑膜所呈现的黏塑性流变行为,选取了Smith流变模型推导得到收敛楔中发生边界滑移后的黏塑性流体动力润滑方程.并针对等温常黏不可压缩流体动力润滑问题,根据润滑膜中切应力分布情况及最大切应力所在位置给出了润滑过程中初始滑移位置,滑移区域发展方式及分布的理论分析.通过联立求解不同区域的黏塑性流体动力润滑方程基础上,对多种膜厚比和运动润滑表面速度下的收敛楔中黏塑性流体动力润滑特性及其边界滑移行为进行分析,并与经典流体动力润滑理论解进行对比,结果表明膜厚比和运动润滑表面速度对黏塑性流体动力润滑性能及边界滑移行为有显著的影响.

英文摘要：

According to the rheological behavior of visco-plastic fluid lubricants in convergent wedge at high-speed and high-pressure,the visco-plastic hydrodynamic lubrication equation considering boundary slip is extracted by selecting the Smith rheological model.And for the hydrodynamic lubrication with constant viscosity and incompressible lubricants at isothermal condition,the initial boundary slip position,the development process and distribution of boundary slip field are determined in the light of shear stress distribution and maximum shear stress position of lubricants.The performance and wall slip behavior of visco-plastic hydrodynamic lubrication in various film thickness ratio convergent wedge at different moving lubrication surface speed are also analyzed and contrasted with the solutions at traditional hydrodynamic lubrication by means of solving visco-plastic hydrodynamic lubrication equations at different fields together,results indicate significant influences of film thickness ratio and moving lubrication surface speed on visco-plastic hydrodynamic lubrication performance and boundary slip behavior.
