三辊非对称滚弯成形的数值仿真及试验验证
Numerical Simulation and Experimental Verification of Asymmetrical Three-roll Bending Process
摘要
Abstract
The stress field of deformation zone,the stain field of upper plate surface and the chan-ges of roll bending forces were analyzed during the asymmetrical and symmetrical roll bending process by the finite element(FE)simulation method.The simulation results show that the bending force dur-ing the asymmetrical roll bending process is larger than that during symmetrical roll bending under the same feed distance of the side roll.Compared to the asymmetrical roll bending process,the longi-tudinal and radial stress in deformation zone in the symmetrical roll bending process are smaller.The forming accuracy of the asymmetrical roll bending process of the pre-bending section is higher than that of symmetrical roll bending process.The experimental verification of a typical plates for the asym-metrical roll bending process was conducted,the result show that the forming error of FEA model is 6.8%.The FEA model has a higher forming accuracy.关键词
