Title:DynamicSimulationAnalysisofK-typeDerrickinSeismicExcitation
Abstract:
Inrecentyears,theoccurrenceofearthquakeshasbroughtsignificantchallengesforthesafetyandstabilityofdrillingoperations.Thedynamicresponseofdrillingequipment,especiallythederrickstructure,underseismicexcitationisofutmostimportanceinensuringthesafetyofpersonnelandequipment.ThispaperaimstoanalyzeandsimulatethedynamicbehavioroftheK-typederrickintheseismicexcitationthroughnumericalmethods.Thestudyexploresthestructuralresponse,suchasdisplacement,acceleration,andstressdistribution,toprovideabetterunderstandingofthedynamicbehaviorofthederrickunderearthquake-inducedloads.
Keywords:seismicexcitation,K-typederrick,dynamicsimulation,displacement,acceleration,stressdistribution.
