摘要 An analytical model based on linear decreasing leveling scheme was proposed to investigate the longitudinally profiled plate leveling process. Considering the variable cross-sectional thickness of longitudinally profiled plate and the dynamic reductions in leveling rolls, the reduction models of upper and lower rolls, the leveling force model and the leveling moment model were established, respectively, based on linear decreasing leveling scheme. Moreover, the finite element model of longitudinally profiled plate leveling process was established based on ABAQUS. Then, the total displacements of upper and lower rolls, the leveling force and the stress distribution of longitudinally profiled plate in the leveling process were calculated. To verify the validity of the proposed models, calculated leveling forces were compared with the measured values, and very good agreements are found. Calculated results show that linear decreasing leveling scheme is suitable for leveling longitudinally profiled plate.
