A theoretical model was established to investigate the effect of the parallel slider surface with triangular cross section short grooves on hydrodynamic pressure performance through solving Reynolds equation by multigrid method.The interaction of the length,width,horizontal and vertical spacing and depth parameters of the short grooves texture on the hydrodynamic pressure performance of friction pair surface was analyzed.Results show that the increasing of the length of short groove texture has limited impact on pressure improvement.Under certain operating conditions,the hydrodynamic lubrication effect is increased first and then decreased,there are optimum groove width,depth and horizontal spacing of short groove texture to maximize hydrodynamic lubrication effect.The hydrodynamic lubrication effect is increased with the decrease of vertical spacing of short groove texture.
