摘要
针对目前船舶排放计算中船舶主机功率的估算问题,基于AIS数据库和长江船舶登记数据库的相关信息,采用数据拟合方法,得到不同船型的主机功率对于船舶主尺度的最优函数;建立船舶的主机功率估算模型,并对模型进行计算验证.实验结果表明,用该方法建立的船舶主机功率估算模型的估算值与实际值之间的误差率在±10%以内,具有较高的可靠性.
In view of the estimation problem of the main engine power in current ship emission calculation,the optimal function of main engine power of different ship types for ship main dimensions was obtained by using data fitting method based on the relevant information of AIS database and Yangtze River ship registration database,and the estimation model of marine main engine was established and verified.The experimental results show that the error between the estimated value and the actual value of the ship main engine power estimation model established by the proposed method is within±10%,which has high reliability.
