摘要
根据船、机、桨关系,以船舶动力装置的能量传递为基础,基于Matlab/Simulink仿真平台建立主机能效模型。以某内河旅游船舶为研究对象,根据船体与主机参数,利用回归多项式法得到螺旋桨敞水特性曲线。在船舶上安装油耗仪等传感器,采集了主机瞬时油耗、船舶对地航速、对水航速等数据,并计算了主机的实际能效。针对实船采集的数据,分析了航道水流速度的分布特征。基于仿真模型,计算了船舶在不同航道水流速度与对水航速下的主机能效,比较分析了实测数据与仿真结果,并对模型进行了验证。本文研究对于提升船舶的营运能效指数具有实际指导意义。
According to the hull-engine-propeller relationship, the energy efficiency model of marine main engine is established based on the energy transfer within marine power plant and matlab/simulink simulation platform. An inland river cruise ship is chosen as a research object, and the open-water characteristic curves of propeller are obtained by using the regression polynomial method according to the parameters of hull and main engine. Several sensors, such as fuel consumption of main instruments, are amounted on the target ship. The instantaneous fuel oil consumption of main engine, the ship speed relative to ground, and the speed to water are collected respectively, and then the real main engine energy efficiencies are calculated. The energy efficiencies of main engine under different water speeds and marine speeds relative to water are calculated based on the simulation model. The actual data and simulation results are compared and analyzed, and the model is verified. The research of this paper has practical guiding significance for improving the operating energy efficiency index of ships.
