摘　　要：用于大型起重机、升船机和矿山提升机等领域的大型提升卷筒， 常采用设有两道环筋， 左右两侧有支轮支承的结构形式。应用弹性基础梁的假设， 全面考虑环筋与支轮弹性的影响， 建立联立方程组， 并编写计算程序， 推导出大型卷筒的解析计算方法。Large drums with supporting wheels at its ends and two ring ribs are commonly used on large cranes,ship￣lifts and elevators for mines.On the assumption that this kind of drum is regarded as elastic base beam,meanwhile considering the affection of the ring ribs and supporting wheels,this paper establishes simultaneous equations,programmes calculation programme and derives analytic calculation method for the large drum design.
