摘要
定常回转直径作为衡量船舶操纵性的一个指标受到人们的普遍重视。为提高船舶的回转性能,基于船舶四自由度的操纵性方程,分析船舶回转直径和回转横倾,讨论影响回转性能的舵型因素,并将其作为优化设计变量,利用Isight优化设计平台,采用遗传算法进行舵型参数的优化设计。通过选取某高速船作为优化对象,利用该方法进行舵型优化后,回转直径及回转横倾都减小。表明借助Isight的优化功能可以实现船舶操纵性能的优化。
Constant turn diameter is paid attention as a maneuvering criteria. In order to increase turning capability of ship, it is to analyze the turning diameter and turning heel and to discuss the elements of turning capability due to rudder parameters and define them as optimization variable, based on four freedom maneuvering equation. It is＇ to use genetic： arithmetic on Isight optimization platform to optimizing design the parameters of rudder. A high-speed vessel is considered as an optimization object, the turning diameter and turning heel are diminished by the method. The results indicate that maneuvering optimization can be achieved through lsight optimization design function.
