为快速确定水面拖曳系统龙须缆的稳态运动参数,建立拖缆三维稳态平衡微分方程。根据拖缆两端的边界条件,利用二分法和龙哥库塔方法,对拖缆微分方程进行积分求解,确定水面拖曳系统中龙须缆的构型及稳态运动参数。以具体的拖曳实例为例进行数值仿真计算,分析龙须缆物理参数变化对系统稳态运动的影响。结果表明,运用这种算法,可以在拖曳系统初步设计阶段快速确定系统索具的参数,并能满足系统设计要求。

In order to quickly determine the steady state motion parameters of the surface towed system with bridle configuration, the towing steady-state equilibrium differential equation is established. The differential equations are solved under the boundary conditions at the ends of the towing lines by both bisection method and 4th order Rnnge-Kutta method, to determine the towing bridle configuration and the steady state motion parameters. The numerical simulation was carried out and the effect of physical parameters of the towing bridle on the steady state motion of the system is analyzed. The simulation results prove that this algorithm can be used to determine the parameters of the systems quickly for preliminary design.
