| 摘 要： | 研究了水面波浪对水下拖缆的干扰。首先基于集中质量法给出了三维非均匀拖缆在规则波作用下的数学模型,然后通过四阶龙格库塔方法进行数值求解,并根据仿真计算讨论了拖缆在不同波浪作用下的稳态响应特性。仿真结果表明,水下拖缆在规则波的作用下,不仅作近似的简谐振动,还会在横向、垂向产生一个偏移量,且随浪向角的变化呈现不同的响应特征。

| Abstract: | In this paper,the effect of surface wave acting on a towed cable is investigated.A mathematical model of 3-D cable is presented based on the LPM(Lumped Parameter Method),which can be solved by 4th-order Runge-Kutta method.Then the steady response character of the towed cable is discussed based on simulation calculation.The simulation result shows that,when affected by regular waves,the cable is forced to fluctuate almost harmonically with a displacement occurred in transverse and vertical directions.It also reveals that the character varies with different wave direction angles. |
