| 摘 要： | 借鉴在船体结构中成熟运用的有限元法,融合刚体动力学的仿真分析手段,利用Matlab软件对两条水下作业的缆绳进行仿真分析,得到缆绳随时间变化形态,从而判断双缆是否会在水下发生干涉。文章首先分析了船舶运动的对缆绳投掷点的影响,其次给出了缆绳在水下的动力学模型,最后通过仿真得出缆绳在水下的形态。

| Abstract: | The underwater operations of two cables are simulated and analyzed by Matlab together with the simulation analysis method of the rigid body dynamics based on the fi nite element method(FEM)that has been widely used in the hull structural design.The obtained variation of the cable posture with time can determine whether the double cable will interfere with each other underwater.It fi rstly analyzes the infl uence of the ship motion on the cable launching point,and then builds the dynamical model for the cables underwater.Finally,the cable posture underwater is obtained through the simulation. |
