为了提高轴承的摩擦学性能，工程上的织构面和滑动面受到了广泛的关注。本文对滑移表面和织构表面的摩擦学特性进行了比较研究。分析结果表明，表面织构和边界滑移对滑动轴承摩擦学性能的影响非常相似。对于确定的表面织构，只有一个滑移速度值才能使织构表面和滑移表面的摩擦学性能一致。得到了滑移速度与织构结构参数的对应关系，滑移速度的大小与其位置等织构几何参数直接相关。该研究将有助于我们进一步了解边界滑移与表面结构的关系以及滑移现象。
Close attentions have been widely paid to the engineering textured and slip surfaces for improving bearing tribological performances. Comparison studies on the tribological characteristics of slip and textured surfaces are carried out in this work. The analysis results point out that the influences of surface texture and boundary slip on tribological performances of slider bearing are strongly similar. For the determinate surface textures, there is one and only value of slip velocity to make the tribological performances of textured and slip surfaces in agreement. The corresponding relation between the slip velocity and the texture structure parameters is also obtained, and the size of slip velocity is directly related to the texture geometry parameters including its position parameters. This study will help us to further understand the relationship between boundary slip and surface texture and also the slip phenomenon.
