摘　　要：水动力性能是影响水面船舶航行特性的重要因素之一,其与船的主要要素、船体型线、总布置等有密切关系,并对水面船舶的安全性与适用性有重要影响。基于模糊数学中的层次分析法,结合模糊评价隶属度函数,提出一个船舶水动力综合评价方法,详细总结船舶水动力评价指标体系,分析影响目标水动力性能的因素,并使用该评价方法对一典型船舶进行评估,验证方法的可行性,并且根据评估结果对水动力设计提出建议。研究表明,采用所提方法可以获得理想的船舶水动力性能评价结果,该结果可为船舶设计提供参考,具有实际应用价值。The hydrodynamic performance is one of the important factors that affect the navigation characteristics of surface ships.They are closely related to the main elements of the ship,the hull line,the general layout,and other aspects,and impose an important impact on the safety and applicability of surface ships.Based on the analytic hierarchy process(AHP)in fuzzy mathematics,combined with fuzzy evaluation membership function,a comprehensive evaluation method of ship hydrodynamic force is proposed.Firstly,the ship hydrodynamic evaluation index system is summarized in detail.Then,the factors affecting the hydrodynamic performance of the target are analyzed.Finally,in order to verify the feasibility of the proposed method,the method is used to evaluate a typical ship,and the hydrodynamic design recommendations are proposed according to the evaluation results.The results show that the proposed method can obtain ideal results of ship hydrodynamic performance evaluation.The results can provide references for vessel design and have practical application value.
