【摘要】：文章考虑缆绳经受的法向与切向流体阻力,在自然坐标系下推导了任意海流中缆绳的动力学方程。建立了中性缆在均匀、线性及组合海流作用下缆形与张力的参数表达式。参数表达式给出了对应海流作用下缆形及张力的物理规律,从而为参数迭代求解时迅速收敛指明了数学途径。自行编制程序,算例的定量结果进一步验证了其物理规律,也表明在长缆绳下,忽略切向阻力在工程上是不合适的。
[Abstract]:Considering the cable subjected to normal and tangential fluid resistance in natural coordinates deduced dynamic equation of arbitrary cable was established. The current neutral cable in uniform, cable tension and parameter expression of linear and combination of ocean currents. The parameters given the laws of physics and corresponding flow under the action of sea cable tension the parameters of Iterative Solutions so as to converge quickly pointed out. Mathematical way of self programming, the quantitative results further verify the laws of physics, but also that in long cable, ignoring tangential resistance in engineering is not suitable.
