摘　　要：阐述了钢丝绳卷扬式垂直升船机主提升机卷筒结构的载荷及应力分布特点,应用国内和国际有关金属结构疲劳强度的设计规范,对部分已建升船机主提升机卷筒结构的疲劳特性进行了分析,在此基础上提出了升船机主提升机大型焊接卷筒结构的疲劳强度计算方法.In this study,the loading and stress distribution features of drum structure are speculated for main hoister of steel-rope-winding vertical shiplift. By applying domestic and international design specifications on metal structural fatigue strength, the drum structure fatigue properties are analyzed on existing shiplifts. Based on this notion, a fatigue strength computational method is postulated for large- scale welded drum structures.
