摘　　要：采用有限元数值模拟与实验研究方法,模拟分析了厚壁筒体翻孔工艺过程材料塑性变形规律及特点,研究了不同温度条件下工件预加工孔型、孔径等对厚壁接管成形尺寸的影响。研究结果表明,模拟与实验结果一致,当预加工孔型为反锥型且平均孔径为11?时,厚壁筒体翻孔后的接管尺寸符合要求。The forming mechanism of hole flanging process on a thick-wall heavy cylinder is simulated, and influence of the workpiece＇s preparatory hole diameters and passes on the hole flanging process is investigated by experiment and numerical simulation in the paper. The results show that experiments are accordant with numerical simulation and when the preparatory hole is reverse-conical and its mean diameter is 11 mm, acceptable nozzle sizes can be obtained after hole flanging on thick-wall cvlinders.
