Taking the effective width of 1600 mm even pad roller as the research object, the FEA (finite element analysis) model of hydraulic oil within even pad roller was established based on finite element software (i.e., Fluent), the effect of the oil pressure distribution on the axis was calculated by changing the roll speed, oil pump pressure and cylinder pressure. The even pad roller was simulated by the software ANSYS/LSDYNA, and to research the changes of the force on fabric in width direction under different oil pump pressure and cylinder pressure. Results showed that the changes of the rotating speed and the external load could cause the oil pressure fluctuation in the oil chamber, but the fluctuation of the oil pressure is relatively small. In addition, the force applied on the fabric in zonal direction was homogeneous under certain oil pump pressure and cylinder pressure. When the oil pump pressure was kept constant and cylinder pressure got increased, the fabric force would get increased at the fabric center area. When the oil pump pressure was increased and the cylinder pressure was kept constant, the fabric force got increased at the edge of the fabric. In this study, the force of each rolling point was obtained, which can provide reference for the precision control of pickup.
