摘要
海洋缆索广泛用于海洋工程领域,海上作业过程中海缆在波浪、流等动力因素作用下容易产生显著的动力响应。为保证海上作业的安全,需要对海缆的动力响应进行有效的分析和研究。首先介绍了缆索的通用弹性动力学方程,然后给出了用凝集质量法求解此方程的模型,算法采用四阶龙格库塔法,利用Matlab仿真计算了水下拖缆回转的形态,经验证,结果有效。由此可得到凝集质量法在解决缆索动力问题中,也是一个很好的选择。
The marine cable is wildely used in ocean engineering field, which is easy to have significant dynamic response due to dynamic factors such as waves and flow during offshore operation. In order to ensure the salty of offshore operation, the dynamic response of the morine cable should be analysed and studied effectively. This paper firstly introuduces the cable＇ s general elastic dynamics equation, then the lumped mass method is used. The algorithm used is the fourth-order runge-kutta method. The program simulates a circular maneuver of the towed cable by Maflab. Analysis indicats that the result is effective. So the lumped mass method is a better choice in solving the cable dynamic problems.
