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.
