摘　　要：基于ABAQUS/Explicit显示动力模块对DP980高强钢定模动辊变截面辊弯成形建立有限元模型,分析板材成形后的等效应力、等效塑性应变及截面厚度的分布特点,并进行安全校核。获得了轧辊成形力与板材的回弹量,为轧辊设计提供了依据。通过实验验证了定模动辊变截面辊弯成形工艺的可行性及有限元分析结果的可靠性。This paper expounded the characteristics of variable cross-section roll forming with static mould and kinetic roll. The finite element model of variable cross-section roll forming with static mould and kinetic roll about DP980 high strength steel was established based on ABAQUS/Explicit. The whole process simulation was done so as to analyze the distributions of equivalent stress, equivalent plastic strain and section thickness of the formed plate, and to make safety checking. The forming force and springback of forming section were obtained, which could provide reference for design. The feasibility of variable cross-section roll forming with static mould and kinetic roll and the reliability of the finite element result were verified by the experiment.
