织构流体动力润滑接触越来越受到人们的关注。使用具有不同形状的微腔（纹理）和在纹理区的不同位置处的纹理表面可以是改善轴承性能的有效途径。本研究探讨纹理位置对流体动压径向轴承性能的影响。采用数值模拟的方法分析了圆柱织构形状对流体动压滑动轴承特性的影响。理论结果表明，通过在接触表面上适当地布置织构区域，可以改善最重要的特性。(C)2010爱思唯尔有限公司版权所有。
A growing interest is given to the textured hydrodynamic lubricated contacts. The use of textured surfaces with different shapes of microcavities (textures) and at different locations of the texture zone can be an effective approach to improve the performance of bearings. The present study examines the texture location influence on the hydrodynamic journal bearing performance. A numerical modelling is used to analyze the cylindrical texture shape effect on the characteristics of a hydrodynamic journal bearing. The theoretical results show that the most important characteristics can be improved through an appropriate arrangement of the textured area on the contact surface. (C) 2010 Elsevier Ltd.
