摘要
水流阻力会对船舶航行造成一定阻碍,在浅水狭航道内,水流阻力影响变得格外显著,为此提出水流阻力对浅水狭航道船舶航行速度的影响研究。在静止水域中,通过质点化分析方法,研究水流对船舶流向行驶以及渡河行驶的影响;流动水域中,使用力学分析框架,研究逆向行驶以及同向行驶水流阻力变化,通过力学坐标系,探究渡河过程中水流阻力的变化对船体造成的影响。试验结果表明,分析结果明确有效,并且分析结果的多样性为浅水狭航道船舶航行提供理论支撑。
Flow resistance will cause certain obstacles to navigation of ships, narrow channel, the water is shallow water resistance becomes particularly significant, therefore put forward flow resistance on shallow narrow channel research and the influence of ship speed. In the static water, the influence of water flow on the direction of ship and crossing is studied by means of qualitative point analysis. Flowing waters, the use of mechanical analysis framework, research direction and the direction flow resistance change, through the mechanical system, to explore the flow resistance in the process of crossing the river changes on the impact of the hull. The test results show that the analysis results are clear and effective, and the diversity of the analysis results provides theoretical support for the navigation of shallow water.
