摘　　要：运用有限元软件ANSYS/LS-DYNA和ETA-DYNAFORM对纵向拼焊板的V形自由弯曲及其回弹过程进行了模拟分析。重点就纵向拼焊板V形自由弯曲的成形特点和影响回弹的主要因素进行了研究,通过分析可知,对纵向拼焊板V形件自由弯曲回弹影响较大的参数为拼焊板的凹模跨度、材料性能和厚度比,而模具的圆角半径、摩擦系数的影响较小。The longitudinal tailor-welded blanks v-shape free bending and springback were simulated by useing the FEM software ANSYS/LS-DYNA and ETA-DYNAFORM.Analysis focused on the shaping characteristic and springback of and longitudinal tailor-welded blanks v-shape free bending.According the analysis,the factors of tailor-welded blanks span of die,different materials and sheet thickness rate had great influence,while the arc radius of die and friction cofficient were had little influence.
