【摘要】：建立船舶推进系统能量耗散分析模型,运用仿真的方法对船舶推进系统整个航次内的能量耗散进行研究。通过对推进系统能量传递过程进行分析,将能量耗散因素分为固定能量消耗和额外能量消耗;分别对坐标系、环境模型、船体运动和推进系统进行研究,建立推进系统能量分析模型;结合欧洲中期天气预报中心(European Centre for Medium Range Weather Forecasts,ECMWF)的气象信息,对目标船在新加坡—香港航线上的航行过程进行仿真研究。计算实例显示:在轻浪海况、主机设定负荷为70%时,推进系统固定能量消耗所占比例为86.7%~89%,主要受航速影响;额外能量消耗占11%~13.3%,受海况、操舵及航线综合影响。利用该模型对不同航线进行分析,可预报航期,并对航线中导致能耗升高的因素进行分析,为优化航线设计提供依据。
[Abstract]:The energy dissipation analysis model of ship propulsion system is established, and the energy dissipation in the whole voyage of ship propulsion system is studied by means of simulation method. By analyzing the energy transfer process of propulsion system, the energy dissipation factors are divided into fixed energy consumption and extra energy consumption. The coordinate system, environment model, hull motion and propulsion system are studied, and the energy analysis model of propulsion system is established. Based on the meteorological information of the European Center for Medium-Term Weather Forecast (European Centre for Medium Range Weather Forecasts,ECMWF), the navigation process of the target ship on the Singapore-Hong Kong route is simulated. The calculation example shows that when the load of the main engine is 70, the proportion of the fixed energy consumption of the propulsion system is 86.7%, which is mainly affected by the speed of navigation. Additional energy consumption accounts for 11 / 13 / 3, affected by sea conditions, steering and shipping. The model can be used to analyze the different routes and forecast the flight period, and analyze the factors that lead to the increase of energy consumption in the route, which provides the basis for the optimization of the route design.
