摘要
对舵系能耗的构成进行计算分析,结合船舶操纵运动数学模型(MMG)建立舵系能耗计算方法,针对具体算例求解以最小舵系能耗为目标的最优操舵策略,讨论相关变量条件对操舵策略及舵系能耗的影响。结果表明:该计算方法具有可行性;对于算例船舶,以10°舵角操舵是使艏向角改变60°的最优操舵策略;不同的舵压力中心位置、舵阻力特性和初始航速条件不会改变算例船舶给定目标任务下的最优操舵策略。研究结果可为船上智能驾驶系统或驾驶人员做出操舵决策提供有效的算法支撑。
The energy consumption of rudder system is calculated and analyzed and the calculation method of rudder system energy consumption is established based on ship manoeuvring mathematical model Group(MMG).Aiming at specific examples,the optimal steering strategy aiming at minimum rudder system energy consumption is solved,and the influence of relevant variable conditions on steering strategy and rudder system energy consumption is discussed.The results show that the computing method is feasible.For the computing case,the best steering strategy to turn the ship bow 60°is steering with 10°rudder angle.Different pressure center and drag characteristic of rudder,initial speed condition of ship do not change the best steering strategy under the given task of the specified computing case.The computing method can be an effective support of computation for the intelligent navigation system or navigator on board when making steering decision.
