旋转机械转子动静碰摩分析及其振动控制的开题报告 Title:AnalysisofDynamicandStaticCollisionFrictionofRotatingMachineRotorsandItsVibrationControl Introduction: Rotatingmachinesplayasignificantroleinvariousindustrialapplications,andtheirproperfunctioningisessentialforthesmoothoperationofmachinery.However,thevibrationscausedduetothedynamicandstaticcollisionfrictionoftherotatingmachine'srotorsposeasignificantchallengeinmaintainingtheirperformanceanddurability.Thevibrationscancauseseveralissues,suchasnoise,higherstressonmachineparts,andevencompletemachinefailure. Theproposedresearchaimstoaddressthischallengeandprovideaneffectivesolutionforcontrollingthevibrationscausedbythedynamicandstaticcollisionfrictionoftherotatingmachine'srotors.Theresearchintendstoanalyzethetheoreticalandexperimentalaspectsofrotors'dynamicandstaticcollisionfrictionandhowitcausesvibrations.
