摘要
为了加强极地船舶船首强度,对极地航线冰况进行研究,提取真实极地航线的海冰数据,建立船舶航行冰况频谱表。对船舶首部采用构型全参数化设计,可保证在首部光顺的前提下进行自由变形。评估函数引入多目标线性规划思想,通过智能优化算法建立优化模型,最终建立极地船舶航行多冰况抗冰性能总收益最优的船舶型线优化设计方法。文中方法可对极地特定航线下的船首抗冰强度起到较好的优化作用。
In order to strengthen the bow strength of polar ships,this paper studied the ice conditions of polar routes,extracted the sea ice data of real polar routes and established the frequency spectrum table of ship sailing ice conditions.The full parametric design of the configuration of the ship's bow ensures that the bow can be freely deformed under the premise of smoothness.The idea of multi-objective linear programming was introduced in the eva-luation function,and an optimization model was established through an intelligent optimization algorithm.Finally,it established the optimal design method of the ship shape line with the best total income of the polar ship sailing in multiple ice conditions.The proposed method has a good effect on optimizing the ice-breaking capability of the bow under specific polar routes.
