For pressure vessel develops increasingly toward large-scale and high parameter,process parameters of four roller plate bending machine were difficult to specify and rolled plate that meets the requirements was difficult to acquire.The finite element model of roller and plate were established to dynamically simulate the stress distribution of the rolls and plate when rolling plate,to attain the location of maximum stress.Results show that the stress of upper roller and side-roller is less than the lower roller,the maximum is located in the junction of lower roller and plate,and there are straight sections on both side of plate.The study is significantly important to the actual production.
