摘　　要：为解决轴系设计阶段各方案的评价标准问题,提高舰船轴系寿命周期的效费比,在分析状态评估方法研究现状的基础上,给出轴系方案评价指标体系构建方法及指标权重计算方法,提出轴系设计状态模糊综合评价方法。以某轴系2种方案为对象,建立轴系设计状态评价指标体系,应用三角模糊层次分析法和熵权法确定指标主客观权重,采用“加法”集成法确定各评价指标的综合权重,应用模糊综合评价法对2种方案进行综合评价,可得方案1和方案2的优良率分别为0.515 0和0.715 6,差等级率分别为0.086 5和0.041 3。研究成果可为轴系设计质量的提高提供新的理论支撑。In order to solve the evaluation standard problem of each scheme in shafting design stage and improve the cost-efficiency ratio of marine shaft system life cycle, based on the analysis of the status quo of state evaluation methods, the construction method of evaluation index system of shafting scheme and the calculation method of index weight were given,and the fuzzy comprehensive evaluation method of shafting design state was put forward. The evaluation index system of shafting design status was established based on two schemes of a shafting. The subjective and objective weights of the indexes were determined by triangular fuzzy analytic hierarchy process and entropy weight method, and the comprehensive weights of each evaluation index were determined by addition integration method. The fuzzy comprehensive evaluation method was used to comprehensively evaluate the two schemes. The excellent and good rates of scheme 1 and Scheme 2 are 0.515 0 and 0.715 6, and the poor grade rates are 0.086 5 and 0.0413. The research results can provide new theoretical support for improving the design quality of marine shaft system.
