摘　　要：通过建立内河客船在规则波中的横摇频幅响应模型,将船舶倾覆概率表达为横摇角概率密度函数的积分,提出适用于船舶初步设计阶段的内河客船倾覆概率计算模型。采用一艘长江干线旅游客船作为母型船,将倾覆概率作为安全性指标,融入优化决策过程中,与其他技术、经济性指标进行整合,构建多目标决策问题,对母型船进行主尺度优化。结果表明,基于完整稳性倾覆概率风险的主尺度优化方法,能够克服传统优化方法的弊端,使得完整稳性风险在初步设计过程中得以被正确评估,从根本上提高设计方案的完整稳性性能。Through the establishment of the roll frequency response model of inland passenger ship in regular beam waves,the ship capisizal probability is expressed as the integration of roll angle frequency function and the capsizal probability model of inland passenger ship applicable to the preliminary design stage is put forward.One luxury cruise ship on the Yangtze River is taken as a parent ship.Being as a safety index,the capsizal probability is merged into the optimization decision-making procedure,and integrated with other technical and economic indexes.Then a multiple-criteria decision making problem is set up and the parent ship’s principal dimensions are optimized.Results show that based on the principal dimension optimization method of intact stability capisizal probability risk,disadvantages of traditional optimization method can be overcame,which enables the intact stability risk to be correctly evaluated in the preliminary design stage,and thus the intact stability performance of the design can be improved fundamentally.
