摘　　要：多道次弯曲是大口径直缝埋弧焊管关键生产技术。由于弯曲成形中卸载后的弹性恢复影响焊管的最终成形尺寸,预测管坯在多道次成形后的最终形状成为本论文的研究目标。采用有限元分析方法,针对壁厚为14.6mm、直径为508mm的X-70管线钢的成形进行了仿真研究,找到了最佳的上模位移量,数值模拟结果与生产实际吻合较好。Multi-pass bending is the key manufacturing technology of large-diameter straight seam submerged arc weld （LSAW） pipes. The aim of this investigation is to predict the final geometry of the pipe after forming because the considerable elastic recovery after unloading affects the precision in dimension. In this investigation, the JCO forming process for X-70 pipe with wall thickness of 14.6 mm and diameter of 508 mm was simulated using finite element analysis method based on the basic theory of bending. The optimum punch displacement value was obtained, and the simulated results are in good accordance with the experimental results.
