Abstract：

Rollers are important components of bending machine with larger quality. Therefore, under the promise of meeting the work requirements, to reduce the quality of rollers can save the production cost effectively. The bending process of rollers was numerically analyzed by the nonlinear dynamic analysis software ANSYS and Workbench, and its deformation was obtained. Then, its structure was optimized by the Design Exploration optimization analysis module in Workbench. Therefore, the total mass of the rollers was reduced from the original 10080 kg to 8858 kg, while the rollers length was reduced from the original 2.2 m to 2.06 m. The result indicates that the deformation of rollers can be analyzed by nonlinear dynamics analysis method. Thus, after Workbench optimization, the mass and size of rollers are smaller than the former, and the production cost is cut down.
