本文提出了一组弹性流体动力润滑（EHL）分析，以评估微底形状对错位人字形槽轴向活塞轴承性能的影响。由于在人字形槽中引入了耗时的弹性流体动力润滑（EHL）任务，复杂的底部形状、旋转组合轴向运动和不对中需要高速计算。因此，提出了一种新的并行弹性流体动力润滑（EHL）数值算法，该算法比常规的超松弛（SOR）方法具有更高的计算速度。结果表明，人字槽底部形状对偏心人字槽轴向柱塞轴承的润滑性能有显著影响。与半椭圆、等腰三角形和直角三角形底部形状相比，矩形和左三角形底部形状涉及微阶梯轴承效应，其可以显著改善润滑性能。
This paper presents a group of elastic Hydrodynamic lubrication (EHL) analyses to evaluate the effects of micro-bottom shape on the performance of misaligned herringbone grooved axial piston bearing. Due to the time-consuming elastic Hydrodynamic lubrication (EHL) tasks introduced in herringbone grooves, complex bottom shape, rotation combined axial movement, and misalignments require high-speed computation. So a new parallel elastic Hydrodynamic lubrication (EHL) numerical algorithm is proposed, which exhibits higher computing speed than the normal successive over relaxation (SOR) method. The results suggest the bottom shapes of herringbone grooves significantly affect the lubrication performance of misaligned herringbone grooved axial piston bearing. Rectangle and left triangle bottom shapes involve a micro-step bearing effect which can significantly improve the lubrication performance, comparing to semiellipse, isosceles triangle, and right triangle bottom shapes.
