摘要
本文根据起重机卷筒的受力特点．提出了更加精确的简化荷载，并考虑了简壁与侧板联结处的局部变形，用内力分配法推导出了更精确的强度计算公式。它对卷筒设计具有指导价值。
ased on the characteristics of force of engineering hoist reel and considering partial deformation of reel wall and side plate,the more exact simplified load is presented. The exact strength calculation fotmula is deducted by the method of internal force distribution. It has a guiding value to design the engineering hoist.
