船舶水下拖带缆-体系统的操纵运动分析

Manoeuver Movement Analysis on Ship Towing Underwater Cable-Body System

提出了船舶水下拖带缆-体系统的时域分析法,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,忽略弯曲刚度.采用变步长4阶龙格———库塔法积分系统运动方程.计算了2个实例以实证程序的可靠性,程序可广泛用于系泊、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阶段.

Time domain analysis is applied to Ship Towing Underwater Cable-Body System and a FORTRAN-77 computer program is given. A Lumped parameter model is used to describe the cable-body system. The cable is taken to be round, extensible and bending rigidity negligible. The Fouth Runge-Kutta method is used to integrate the motion equation of the system. Two examples are also given. The program can be widely used to analyze mooring lines, towing and ROV umbilical cables with series-connected ocean cable-body system in the primary design stage.
