Abstract：

With the rapid development of ship building industry，petrochemical engineering, boiler and pressure vessel, the ultra-large type CNC marine roller machine has been one of the important development directions in the field of roller machine. The disadvantages of currently design methods of roller machine were analyzed，and the mechanical model of upper roller was established. Based on the working principle of three-roll roller machine， the force situation of upper roller was analyzed and calculated. The uniform load and six assumed concentrated forces impacted on upper roller were simulated by assuming the values of a series of reacting forces，and the reflection of roller which is the nearest to the maximum reflection was found，then the concentrated forces for the six supporting points were approximate calculated by inverse method. Finally, by ANSYS simulation，the obtained concentrated forces were impacted on the top beam to ensure that the reflection of top beam was smaller than that of the upper roller. Then, the inertia moment of top beam was adjusted, and the structure was optimized.
