摘　　要：为了解决船舶系泊安全问题 ,从定量上了解缆绳受力状况 ,推导出码头系泊船系缆的悬垂线方程 .根据船舷导缆孔和码头系缆桩的相对位置迭代计算出缆绳张力及系缆拉伸变形 .并简要分析了不同出缆长度情况下 ,船舶运动对缆绳张力的影响 .模拟计算表明 ,长的、弹性好的、单位长度重量大的系船缆更有利于缓冲外力、吸收船舶动能 。An equation is introduced in this paper to describe the shape of the mooring line which is lead from a fair leader to a bollard. The tension of the line is then calculated in accordance with the locations of the fair leader and the bollard, considering the transformation of the line due to the tension. The relationship between ship movement and the tensile force is still analyzed in the case of different length of the mooring line. The numerical results show that longer, better elasticity and heavier mooring lines take higher efficiency to fasten the ship: being good for absorbing the kinetic energy of the ship and moderating the impact on the line, opposite to the shorter,worse elasticity and lighter ones.
