SHIPENGINEERING船舶工程Vol.45No.12023总第45卷，2023年第1期—6—基于FMEA和模糊TOPSIS的波浪能发电装置风险评估方法李蒙，王海峰，汪小勇，段云棋，崔琳（国家海洋技术中心，天津300112）摘要：波浪能发电装置结构复杂，运行环境恶劣，易受到风浪冲击和海水长期浸泡腐蚀的威胁，对装置进行可靠性分析时面临系统故障模式复杂、故障记录少等问题，海洋工程领域传统的故障模式及影响分析（FMEA）方法难以对装置系统的风险进行准确评价。基于模糊逼近理想排序法（TOPSIS）提出一种改进的FMEA风险评价模型，采用模糊置信结构对评价因素进行表示，引入评价因素的权重概念，建立风险性能指标的加权规范化矩阵，利用TOPSIS逼近理想解的原理进行风险排序，得到风险优先数，并以浮力摆式波浪能装置为例进行分析，结果表明俘获系统对波浪能发电装置整体的可靠性影响最为显著。关键词：波浪能发电装置；故障模式及影响分析（FMEA）；逼近理想解排序法（TOPSIS）；风险评估中图分类号：P742文献标志码：A【DOI】10.13788/j.cnki.cbgc.2023.01.02RiskAssessmentMethodofWaveEnergyConverterBasedonFMEAandFuzzyTOPSISLIMeng,WANGHaifeng,WANGXiaoyong,DUANYunqi,CUILin(NationalOceanTechnologyCenter,Tianjin300112,China)Abstract:Waveenergygeneratorhascomplexstructureandbadoperatingenvironment,andisvulnerabletothethreatofwindandwaveimpactandlong-termimmersioncorrosionofseawater.Thereliabilityanalysisofthedeviceisfacedwiththeproblemsofcomplexsystemfaultmodeandfewfaultrecords.Thetraditionalfailuremodeandeffectsanalysis(FMEA)methodinthefieldofmarineengineeringisdifficulttoaccuratelyevaluatetheriskofthedevicesystem.AnimprovedFMEAriskevaluationmodelisproposedbasedonthefuzzyTOPSISmethod.Thefuzzyconfidencestructureisusedtorepresenttheevaluationfactors,theconceptofweightofevaluationfactorsisintroduced,theweightednormalizationmatrixoftheriskindicatorevaluationisusedtoapproximatetheidealsolutionbyTOPSIStoranktherisksandobtaintheriskprioritynumber,andtakingthebuoyancypendulumwaveenergyconverterasanexample,theresultsshowthatthecapturesystemhasthemostsignificantimpactontheoverallreliabilityofthewaveenergyconverter.Keywords:waveenergyconverter;failuremodeandeffectsanalysis(FMEA);t...
