In the present work, theoretical investigation has been performed to predict the influence of spherical textures on the performance characteristics of two-lobe journal bearing system. The flow of lubricant in the clearance space between the bearing and the journal is governed by the Reynolds equation assuming the flow is Newtonian and isoviscous. The Reynolds equation is solved using a finite element method and the static performance parameters of circular/two-lobe smooth/textured journal bearing system have been computed with variation in eccentricity ratio, dimple depth and its location. The numerically simulated results reveal that the partial surface texturing can provide better performance when the textures are created in the pressure build-up region of 126°–286° and the dimple aspect ratio is nearly 1.0.

表面纹理对流体动力两叶轴颈轴承性能特性影响的理论研究

在目前的工作中，已经进行了理论研究，以预测球形纹理对双叶轴颈轴承系统性能特征的影响。润滑剂在轴承和轴颈之间的间隙空间中的流动由雷诺方程控制，假设流动是牛顿和等粘性的。雷诺方程使用有限元方法求解，并计算了圆形/双瓣光滑/纹理轴颈轴承系统的静态性能参数，其中偏心比、凹坑深度及其位置发生了变化。数值模拟结果表明，当在 126°–286° 的压力累积区域内创建纹理且凹坑纵横比接近 1.0 时，局部表面纹理可以提供更好的性能。
