白车身FEMFAT疲劳分析流程

摘要：这份文档是ANSYS13.0版本中AQWA与ASAS两款海洋工程专用模块的更新介绍讲义。内容先概述AQWA专注海洋结构水动力分析，支持频域/时域、多体耦合、系泊与缆索动力学；ASAS面向海洋平台全局结构有限元分析与疲劳校核。13.0版重点实现AQWA全面接入Workbench，新增水动力时域响应系统，强化缆索弯曲刚度、非线性轴向刚度与自定义刚度矩阵。ASAS技术迁移至Mechanical，优化梁单元、波浪理论与土-桩-结构耦合，并新增DesignAssessment设计评估系统，提供FATJACK、BEAMCHECK等专用校核工具。整体完成水动力与结构仿真深度集成，提升海洋工程全流程仿真能力。AQWA&ASASProductUpdatesforANSYS13.0Contents•AQWA&ASASOverview–ProductsandApplicationsAreas–ProductRoadmap•Release13.0Update•OutlookQWA&ASASOverview-MainApplicationAreasOffshoreStructures–Fixed•SteelJackets•Concrete–Compliant•Jack-ups–Floating•FPSOs•SPARS•Semi-Submersibles•TensionLegPlatforms–Risers–OffshoreWindTurbines•Harbours•Ships–Design–OffloadingOffshoreProducts-HowtheyfitwithANSYSportfolioGeneralProducts:•DesignModeler•ANSYSMechanical•CFX/FLUENTVerticalApplications:•AQWA•ASASOffshoreProducts-AQWA•ComprehensiveHydrodynamiccapabilities–Diffraction/RadiationincludingMorisonelements–FrequencyDomainanalysis–Stabilityincludingmooringlines–Timedomainwithirregularwaves–Timedomainwithnon-linearsurvivalwaves–CoupledCableDynamics–Multiplehydrodynamicinteractionandarticulations(upto50structures)–TransferofmotionsandPressurestoASAS&ANSYSFEmodelsAQWA-TypicalApplications•SomeexampleapplicationsOffshoreProducts-ASAS•FEbasedoffshorestructuralanalysissuite–Mainlyusedin“global”designanalysis–Uniquepost-analysisassessmenttoolsspecifictooffshorerequirements•Somekeyfeatures–Coupledwave-structureinteractionwithregular/irregularwaves–Coupledhydro-elasticanalysisfortubularframedstructures–WaveloadingandaddedmassforjacketsandsimilarstructuresSpectralanddeterministicfaftgueofjackets–ToolkittofacilitateusersoftwareintegrationASAS-TypicalApplications•SomeexampleapplicationsProductRoadmap-AQWA•MigrationofAQWAtoWorkbench–AQWAuniqueinANSYS–Providesparameterizationandinterfacing/couplingwithothertools/products(geometry,meshing,solvers)ProductRoadmap-ASAS•TransferofASASuniquesolvertechnologytoANSYSStructuralMechanicsproducts–Neveranylongtermscopefordeveloping/supportingmultipleFEproducts–RecognitionofASASkeyfeatures•CreationofaDesignAssessmentsystemtohandlepost-processingofanalysisresults–Foroffshore,thiscoversloadcasecombinationsandcodechecking•AdditionalProducts–SeparateCodeCheckingandFatigueProductsOffshoreProductsatR13-FeatureSummary•AQWA–AQWAinWorkbench–AQWACoreDevelopments•ASAStoMechanical–BeamModeling–Wavetheories–Soil-Pile-StructureInteraction•DesignAssessment–NewDesignAssessmentsysteminMechanical–AdditionalcodecheckingproductsAQWAinWorkbench-HydrodynamicDiffractionSystemAQWAinWorkbench-HydrodynamicDiffractionSystem•Initialimplementationat12.1ExtendedtocovermostofAQWADiffractionproduct–AQWALINEnowfullyreproducedintheHDsystem(includingrecentcoreenhancementenablingmooringlinerepresentation)–NewQTFandSF/BMGraphs–AQWAWAVEcapabilitiestotransferpressuresetctoMechanicalnotimplementedinWB–butthecapabilitydoesexistandisdocumentedAQWAinWorkbench-HydrodynamicTimeResponseSystem•NewHydrodynamicTimeResponseAnalysisSystem–Timehistoryanalysisofbodies,subjecttoenvironmentalforcesincludingmooringlinesAQWAinWorkbench-HydrodynamicTimeResponseSystem•Inputforthefollowingcompleted:–Cableconnectionsforrigidbodymotion,waveandmooringlineanalysisundervariousoceanenvironments–OceanEnvironmentDefinitionforWind,WaveandCurrent–AdditionalStructureForceTimeHistory–CableWinchingandFailures–Inputofcatenarymooringlines–Realisticviewingofmooringlines–Graphingofvariousresults•Displacement,velocity,accelerationAQWAinWorkbench-HydrodynamicTimeResponseSystemAQWACoreDevelopments•CableDynamics–Bendingstiffnessallowsmodelingofrigidandflexiblerisers(previouslyonlyrigidriserscouldbemodeledusingtethers)–Non-linearaxialstiffnesstoenablemorerigorousmodelingofsyntheticmoorings.Usespolynomialdefinitionoftensionvextension.AQWACoreDevelopments•User-definedstiffnessmatrixconnectingseparateships–Thisenablesmooringsystemtobeincludedindiffraction/radiationanalysis•Responsespectraavailableforanyspecifiedpositiononship(previouslylimitedtoCoG)•Responsespectraavailableforintermediatepositions(connectionpoints)alongmooringlines•ISOwindspectrumdefinitionaddedfordynamicmotionsanalysis•AQWAGraphicalSupervisor(AGS)nowabletopresent/animatecabledynamicsresultsfromintermediatepositionsalongmooringlines–BasedonanalysisresultsorseparatelydefinedboundaryconditionsASAStoMechanical-BeamsandWaveTheories•BeamPost-Processingenhancements–ShearForceandBendingMomentdiagrams•BeamEnd-Releases•WaveTheories•Irregularwaves•ShellNewWave•ConstrainedWaveASAStoMechanical-Soil-Pile-StructureInteraction•Soil/PileInteractionSolver(SPLINTER)enhancedtoworkwithMechanical(viacommandsnippets&Matrix27elements)–PILEGENandPILECALCmacrosincludedwiththeASASinstallation(capabilityonlyavailableviaASASOffshorelicense)DesignAssessment-NewSysteminWorkbench•DesignAssessmentSystem–AvailablewithProfessionalNLSandabove–Post-analysisassessmentsofFEAresults–LoadCaseCombinations•StaticStructural•FlexibleDynamics(ataspecifictime)DesignAssessment-Customization•DesignAssessmentSystem–Advancedpost-processingofFEAresults•Targetedatuserwantingtodo
