ResearchontheVibrationTestofInlandIce-breakingShips
Introduction
Inlandice-breakingshipsareessentialfortransportation,research,andexplorationinArcticregions.Theyarespecificallydesignedtonavigatethroughicywatersandareequippedwithadvancedtechnologiestobreakthroughiceblocksandmaintainasteadycourse.However,theharshandunpredictableconditionsofpolarregionsposesignificantchallengestotheirstructuraldesignandoperation.Theship'sresistancetoicebreakingandvibrationperformancearetwocriticalfeaturesthataffectitssafetyandefficiency.

VibrationAnalysis
Inlandice-breakingshipsaredesignedtowithstandhighimpactloadsandseverevibrationconditions.Theshockandvibrationgeneratedduringthebreakingoficesheetscancausesignificantdamagetotheship'sstructuralcomponents,suchashulls,decks,andmachinery.Therefore,vibrationanalysisiscrucialtodeterminetheship'sstabilityandsafetyduringtheice-breakingprocess.
Thevibrationresponseoftheshipisaffectedbyseveralfactors,suchasiceload,shipspeed,icebreakingperformance,waterdepth,andhullshape.Thevibrationfrequencyiscloselyrelatedtotheship'snaturalfrequency,whichisdeterminedbytheship'ssize,shape,andmaterialproperties.Differentvibrationmodesoftheshipcanbeexciteddependingontheoperatingconditionsandenvironmentalfactors.
