摘　　要：舭龙骨作为一种简单的减摇结构,可有效降低船舶在波浪中的横摇响应,提高船舶耐波性。尤其是对于半潜船,舭龙骨参数的合理选择可有效改善横摇,降低实际营运中货物绑扎量要求,从而降低运营成本。目前船舶设计通常采用经验公式或模型试验来确定舭龙骨参数,存在不确定性和成本高等问题。本文以某10万吨半潜船为研究对象,采用数值模拟方法,对比舭龙骨参数对横摇、横荡的影响,发现舭龙骨的面积、长度和宽度等参数对横摇有显著影响。本文研究结果可为肥大型船舶舭龙骨设计提供参考。As a simple anti-rolling structure,bilge keel can effectively reduce roll response of ships in waves and improve ship seakeeping.Especially for semi-submersible vessels,the reasonable selection of bilge keel parameters can effectively improve rolling,reduce the requirement of cargo binding quantity in actual operation,and thus reduce operating costs.At present,bilge keel parameters are usually determined by using empirical formula or model test in ship design,which could lead to high uncertainty,high cost and other problems.Taking a 100000 DWT semisubmersible vessel as the research object,this paper adopts numerical simulation method to compare the influence of bilge keel parameters on rolling and swaying,and finds that parameters such as area,length and width of bilge keel have significant influence on rolling.The results of this paper can provide ideas for bilge keel design of full formed ships.
