The operating and geometric parameters of textures affect the static, dynamic, and stability performance characteristics of a journal-bearing system. The present work investigates the influence of spherical-, cylindrical-, triangular-, and kite-shaped textures on the performance parameters of a journal-bearing system. The flow of a lubricant is assumed to be Newtonian and iso-viscous. Reynold's equation governing the flow of a lubricant between the space in the bearing and the journal is solved by a finite-element method. The computed results indicate that the spherically textured journal bearing provides better improvement in the performance parameters vis-a-vis other textured bearings. In general, the effect of texture shapes is more pronounced at the aspect ratio of surface textures is 1.0.

纹理的操作和几何参数会影响轴颈轴承系统的静态，动态和稳定性能特性。本工作研究了球形，圆柱形，三角形和风筝形纹理对轴颈轴承系统性能参数的影响。假定润滑剂的流动是牛顿和等粘度的。用有限元方法求解控制轴承和轴颈空间之间的润滑剂流动的雷诺方程。计算结果表明，与其他纹理轴承相比，球形纹理轴颈轴承在性能参数方面提供了更好的改进。通常，在表面纹理的纵横比为1.0时，纹理形状的影响更为明显。
