Design of Wall Thickness of the Main Cylinder of a 300MN Hydraulic Die Forging Press Based on Random Reliability

According to the probability law,the main cylinder wall thickness has been designed,which is only 35% of the originally used,effective reduction of the weight of the main cylinder.The deviation change of the main cylinder wall thickness has some influence on its reliability,it is necessary to control the thickness deviation in the manufacture.
