海洋拖曳系统稳定姿态的影响因素研究

Influential Factors on the Steady State of Underwater Towed System

目前在进行海洋拖曳系统稳定姿态研究时,仅能针对单一的影响变量进行分析,难以将多个相互关联的物理参数作为一个整体进行考虑。鉴于此,根据拖曳系统的受力平衡,建立了海洋拖曳系统运动计算模型;并基于该模型,提取出了影响系统稳定姿态的四个关键因素,实现了多个物理参数的耦合分析。使用四阶龙格库塔法仿真计算了这个四个因素对系统稳定姿态产生的影响。数值结果表明了模型的正确性,并分别给出了各因素对系统稳定姿态的影响规律,为海洋拖曳系统的设计提供一定的理论参考和更加明确的设计依据。

When we research on the steady state of underwater towed system, only one influential factor can be considered normally. In order to consider the physic parameters as a whole in the design and steadystate simulation of underwater towed system, a numerical model for steady-state solution of towed system was presented. Based on this model, four influence factors on the steady-state of towed system were given out and coupling physic parameters can be analyzed as a whole. The numerical model is solved by the Runge-Kutta method and the affections caused by the four influence factors were analyzed. The numerical result showed that the model was correct and rules were given out. This research can be used as the theory model and foundation for designing the underwater towed system.
