摘　　要：航速优化作为内河船舶实现节能减排以及降低运营成本的有效措施之一,深受学术界的关注。本文以航行于长江航道的某7500 t内河散货船为研究对象,以实船设计数据为基础建立船舶阻力-主机-螺旋桨之间的能量传递关系模型;基于长江航道环境数据建立用于航速优化的长江航道数据模型;进一步地,以增广拉格朗日方程(augmented Lagrange equation)以及差分进化(differential evolution)算法为基础设计用于求解内河航速优化问题的ALDE算法。通过选取典型工况,分析7500 t内河散货船往返于江阴港与宜宾港之间的航速优化以及油耗结果。仿真结果表明:所设计的ALDE算法能够有效求解内河航速优化问题;通过实施航速优化,在指定航行到达时间的约束下能够节约2.76%的船舶柴油消耗。本研究可对内河船舶的节能以及降低航运成本起到重要的作用。Speed optimization,one of the effective ways for inland ships to achieve energy saving,emission reduction and reduction of operating costs,has attracted much attention from the academic community.Based on the design data of a 7500 t inland bulk carrier navigating in the Yangtze River,an energy transfer model between ship resistance,main engine and propeller was presented in this paper.A model of the Yangtze River waterway for speed optimization was established on the basis of the environmental data.Furthermore,an ALDE algorithm was designed to solve the inland speed optimization problem by combining the augmented Lagrange equation with differential evolution algorithm.By selecting typical conditions,the speed optimization and fuel consumption results of the 7500 t inland bulk carrier navigating between Jiangyin Port and Yibin Port were analyzed.The simulation results show that the ALDE algorithm can effectively solve the inland speed optimization problem.By means of speed optimization,under the constraints of specified arrival time of the voyage,2.76%of ship diesel consumption could be saved.The research results are of great significance to energy saving of inland ships and reduction of shipping costs.
