为揭示表面织构对滑动轴承摩擦学性能的影响，指导滑动轴承微织构的优化设计，提出双系数数值滑移边界来表征表面织构宏微观相互作用的综合效果，并将其施加到有微织构的轴承表面；采用相变模型描述空化现象，研究了织构区域的位置、面积等宏观参数对滑动轴承承载能力和空穴的影响规律。最后采用文献所述实验轴承进行分析，验证了该双系数数值边界的正确性。研究表明，空穴区域处的织构不会影响润滑液膜压力和轴承承载能力；织构区域前端会产生低压效应而其末端会产生动压效应；织构位于压力上升区域时可以提高承载能力，且承载能力随该区域织构表面面积的增大而增大，但织构位于压力下降区域时将降低承载能力并加剧空化现象。“,”In order to reveal the effects of surface texture on the tribological performances of journal bearings for the micro-texture optimization design,a numerical slip boundary condition with double coefficients was determined to characterize the comprehensive effect of the macroscopic/microscopic interaction and was applied to the journal bearing surfaces with controlled micro-textures.Then,the cavitation was modeled by using a phase change model, and the effects of such macroscopic parameters as the surface texture location and its area on the load-carrying ca-pacity and the cavitation were investigated.Finally,the proposed numerical slip boundary condition with double co-efficients was verified by using an experimental bearing reported in a reference.Theoretical analysis results show that (1 )the surface texture in the cavitation region has no effect on the pressure of the lubrication film and the load-carrying capacity of the bearing;(2)there exists a low-pressure effect at the front of the texture region but a dynamic-pressure effect at the end;(3 )the textures in the hydrodynamic pressure-rising region may increase the load-carrying capacity in a positive correlation with the area of texture surface in this region,while the textures in the pressure-dropping region may reduce the load-carrying capacity and aggravate the cavitation.
