中文摘要：
探索一种可描述缆索系统垂向吊放动力学行为的解析模型。给出它的自封闭方程、固有频率和简谐运动表达式，确定了母船和中际站之间的运动和张力传递函数，模拟结果能很好地符合实验估计值。导出沿着缆索的张力表达式，可用来预测缆索松驰和突变载荷的发生。
英文摘要：
An analysis model for dynamic behavior of an underwater vertically suspended system was explored. The closed form solution and expressions for the natural frequency and harmonics, motion and tension transfer function between ship and cage were found. The results of sinmlation agree well with those estimated from field measurements. An expression of tension along the tether can be used to predict the ampli- tude and frequency of ship motion at which the tether will go slack and snap load will occur.
