摘 要： This work concern with the performance of hybrid circular thrust pad bearing having partial and full textured surface, operating with power law lubricant has been studied. The governing Reynolds equation is non-linear with pressure. Finite element method with JFO boundary conditions has been implemented to obtain fluid film pressure on the bearing surface and cavitation zone. The numerically simulated results reveal that, among the different non-Newtonian lubricants, the dilatant one provides the minimum value of frictional power loss. Results show that surface texture and the behavior of lubricant significantly changes the frictional power loss and other performance parameters. It is expected that the result obtained will be very much quite useful for bearing designer and academic community. (C) 2015 Elsevier Ltd. All rights reserved.

本研究探讨了具有部分和全表面纹理的混合式圆周推力垫片轴承在幂律润滑剂作用下的性能。所采用的雷诺方程是非线性的，且与压力相关。通过有限元法结合JFO边界条件，对轴承表面及空化区域的流体膜压力进行了求解。数值模拟结果表明，在多种非牛顿润滑剂中，膨胀型润滑剂能提供最小的摩擦功率损耗。结果表明，表面纹理及润滑剂的行为显著影响摩擦功率损耗及其他性能参数。预计所得成果将对轴承设计者和学术界具有重要参考价值。（C）2015 Elsevier Ltd.版权所有。
