The motion model of the gas inside the porous material was established by the Darcy law,the Reynolds equation of the gas flow was established in the gas film region,and the equations were corrected while considering the velocity slip.The pressure distribution equation in the above two region are coupled,the coupled pressure distribution equation was discretized by the finite element method,and the superrelaxation iteration method were used to solve the gas film pressure distribution of each node.The influence of the velocity slip on the static characteristics of the porous hydrostatic bearing was analyzed.It is found that the distribution of film pressure changes smooth while considering the velocity slip.The load capacity and stiffness was calculated.It is found that when the film gap is less than 15 μm,the load capacity is increased with the film gap due to the the pressure difference caused by eccentricity increase.While the coefficient of velocity slip is less than 0.1,the velocity slip has a great effect on the load capacity.
