摘要
针对某型双加甲板拖网渔船导管桨,建立基于底拖网作业渔船工况和自航工况的综合性船、机、桨优化匹配模型,对船机桨进行多重比较优化。采用导管和大直径螺旋桨,并通过生产实践,验证优化设计的高效性,提高拖网渔船推进系统的效率,增大系柱的拖力。
For a certain type of double-deck trawler, a comprehensive optimal matching model of ship, equipment and paddles based on bottom trawler operating conditions and self-propelled conditions is established. The multiple comparing optimization of the paddles is done. The duct and large-diameter propellers are adopted. Through production practices, the high efficiency of the optimized design is verified. The efficiency of the propulsion system of the trawler is improved and the column drag force is increased.
