机翼壁板参数化有限元模型属性更新研究 Introduction Intheprocessofaircraftdesignandmanufacturing,thewing skinpanelisoneofthemostcriticalcomponentsoftheaircraft. Thewingskinpanelplaysavitalroleintheperformanceofthe aircraft.Itnotonlydeterminestheaerodynamiccharacteristicsof theaircraftbutalsoinfluencesthestructuralintegrityofthewing structure.Inordertoaccuratelyanalyzetheperformanceand durabilityofthewingskinpanel,itisnecessarytoestablishafinite elementmodelofthewingskinpanel. Inthispaper,wefocusonaparameterizedfiniteelement modelofwingskinpanels.Thepurposeofthisresearchistostudy theattributeupdatesoftheparameterizedfiniteelementmodel ofwingskinpanels.Wewillintroducethebackgroundofthe researchandanalyzetherelatedresearchworks.Then,wewill presentthemethodofestablishingtheparameterizedfinite elementmodelofthewingskinpanelandtheattributeupdating method.Finally,wewillshowtheresultofacasestudyand discusstheadvantagesanddisadvantagesofthepresented method. Background Traditionalfiniteelementmodelingofwingskinpanels requiresgeometrymodeling,meshgeneration,materialallocation, andloadapplication.Theseprocessesarecomplexand time-consuming.Furthermore,ifthegeometryofthewingskin panelischanged,itisnecessarytorepeatthemodelingprocess. Theseissueslimittheefficiencyandflexibilityoftraditionalfinite elementmodelingmethods. Withthedevelopmentofparametricmodelingtechnology, researchershaveproposedmethodsforparameterizingthewing skinpanelmodel.Thesemethodscansignificantlyreducethetime andlaborrequiredformodelmodificationandupdate.Moreover, parametricmodelingallowsengineerstoquicklygenerateaseries ofmodelswithdifferentparametersandoptimizethedesignof thewingskinpanel.
