摘　　要：传统船舶建造流程中导流罩与艉轴管分段连接,作业焊接会对艉轴管产生失圆影响,致使施工周期延长且精度下降。本文通过对比分析61000 DWT散货船艉框架和艉部导流罩合拢及艉轴镗孔的作业方法,提出艉部导流罩与艉框架一体后镗孔工艺方案,减小了焊接变形对于艉管精度的影响,缩短施工周期,提高经济效益,为此类船舶建造流程提供参考。In traditional shipbuilding processes,segmented connections between the stern fairing and stern tube often induce out-of-roundness in the stern tube due to welding deformation,leading to prolonged construction cycles and reduced precision.This study proposes an integrated post-boring process for the stern fairing and stern frame by analyzing assembly and boring methods for a 61000 DWT bulk carrier.The approach mitigates welding deformation effects on stern tube accuracy,shortens construction timelines,and enhances economic efficiency,offering a reference for similar shipbuilding workflows.
