Abstract:
Inrecentyears,thedevelopmentandoptimizationofshippropulsionsystemshavebecomeincreasinglyimportanttoimprovetheefficiencyandsafetyofships.Thevibrationproblemoftheship'spropulsionsystemhasattractedmoreandmoreattentionfromresearchers.Inordertosolvethisproblem,thesystemmatrixmethodiscommonlyusedtoanalyzethevibrationcharacteristicsoftheship'spropulsionsystem.Therefore,thispaperwillexplorethedevelopmentofashippropulsionsystemtorsionalvibrationprogrambasedonthesystemmatrixmethod.
Introduction:
Marinepropulsionsystemsareanessentialpartofships,andefficientandreliablepropulsionsystemsarecrucialtotheirperformance.However,itisinevitablethatthepropulsionsystemwillproducetorsionalvibrationsduringtheoperation,whichnotonlyaffectsthereliabilityandsafetyofthepropulsionsystembutalsohasagreatimpactonthecomfortoftheship'spassengers.Therefore,thetorsionalvibrationproblemoftheship'spropulsionsystemhasreceivedmoreandmoreattention.
Thesystemmatrixmethod,asaneffectivemethodforanalyzingthetorsionalvibrationofpropulsionsystems,hasbeenwidelyusedinthefieldofmarineengineering.Themethodusesthesystemmatrixtoestablishamathematicalmodelofthepropulsionsystem,thusprovidingatheoreticalbasisfortheanalysisofthetorsionalvibrationofthepropulsionsystem.
