摘要
提出了海洋缆—体系统的三维动态性能时域分析法 ,并给出了计算机程序。采用凝集参数法模拟了缆—体结构系统 ,缆为圆形截面 ,可伸长 ,不考虑弯曲刚度。采用了四阶龙格—库塔法积分系统运动方程。计算了二个实例以验证程序的可靠性。程序可用于系泊、拖曳、潜器脐带缆等具有组合成分的海洋缆体系统的初步设计。
The present paper gives a time domain analysis method for ocean cable body systems and a FORTRAN 77 computer program. The Lumped parameter method is used to model the cuble body system. The cable is taken to be round and extensible with negligible bending rigidity. The Fouth Runge Kutta method is adopted to integrate the motion equation of the system. The paper gives two examples to illustrate the validity of the model. The program can be widely used to analyze moring lines, towing and ROV umbilical cables with series connected ocean cable body systems in the primary design stage.
