摘　　要：深水铺管用收放(A&R)绞车的动力滚筒与钢丝绳之间力的传递关系是影响滚筒结构参数设计的关键因素。分析了工作状态下钢丝绳在双动力滚筒结构出入端的张力变化,建立了钢丝绳张力与钢丝绳和双滚筒之间的摩擦因数、钢丝绳在卷筒上的包角、双滚筒缠绳层数(绳槽数)等参数之间的关系式,并综合考虑动力滚筒受力进行了ABAQUS有限元强度分析。为深水铺管绞车的设计和校核提供了参考。For deepwater pipe-laying A＆R winch,the tension transmission between traction drum and wire is a critical factor which will affect the design of the drum structural parameters. In the paper,the tension variations on input and output ends of the wire line on the traction drum are an- alyzed, and taking the coefficient of friction and arc of contact between the steel wire and the traction drum as well as the rope groove number/layer number into account,the relationship between the steel wire tension and the stresses in the double traction drum of the deepwater A＆R winch is established. Combining with comprehensive consideration on other forces, the finite element analysis （ABAQUS） on the drum was made tO obtain valuable reference for design and check of the drum.
