摘要
钢管空拉减径,伴随着管壁变化。本文用理想塑性材料取代强化材料,分析了锥模空拉钢管壁厚变化规律,找到了临界相对壁厚的表达式。理论值与实际值吻合较好。
The change of steel tube wall thickness during sinking is studied.The factors influencing wall thickness are analyzed,and the critical relative wall thickness is determined.Calculated values agree well with experimental ones.
