随着人类对海洋资源的需求日益增加,海洋勘探拖缆的研究被越来越多的人所重视。对拖缆动态特性的把握和预判成为了一个非常关键的问题。基于Ablow的经典模型,运用了微元法对拖缆阵列建立三维模型,在时域上采用了广义α算法对拖缆三维动态方程离散求解,通过程序编译,实现了对拖缆在变速直线航行以及回转航行工况下的仿真计算,为深入研究制定拖缆动态控制策略提供了依据。
With the increasing demand of human resources for marine resources, the research on marine exploration streamers has been paid more and more attention by people. To grasp and predict the dynamic characteristics of streamers has become a very crucial issue. Based on Ablow’s classical model, a three-dimensional model of the towing cable array is established by using the method of differential equations. In the time domain, the generalized α algorithm is used to discretely solve the three-dimensional dynamic equation of the streamer. Through the program compilation, As well as the simulation calculation under the condition of rotary navigation, which provides the basis for further study on the development of dynamic control strategy of streamers.
