【摘要】 减摇组合附体的型式、尺寸、安装位置等对其减摇效果和船舶水动力性能都有影响,本研究尝试应用优化设计的方法对附体水动力性能进行优化设计。选择了附体在静水中的阻力值来衡量快速性能,一定攻角下的升力值来衡量耐波性能,以升力与阻力的比值为衡量附体优劣的评价指标。附体阻力与升力的数值计算利用了商用软件CFD。采用遗传算法进行附体尺寸的优化。优化目标是结合某船型,找出安装于该船型上的最优附体尺寸方案。
【Abstract】 The form,size,and position of built-up appendage have great influence on the hydrodynamics of hybrid monohull.In this paper,the optimization design method is used to improve the hydrodynamic performance of the appendage.The ratio of lifting force and resistance of the appendage is set as the evaluation index for the seakeeping performance and resistance performance of the hybrid monohull.The lifting force and resistance of the appendage are calculated using the CFD software,and the Genetic Algorithms is used for the optimization.After the optimization,the best configuration of the appendage is proposed for the hybrid monohull.
