摘    要:挤压油膜阻尼器设计不当,会导致功能失效。创建了弹支挤压油股阻尼器的双稳态区域图和减振失效边界围。只要轴承参数B和质量估心率U值不在双稳态区域内,便不会出现双稳态特性;离开诚振失效的边界,便可有效的减振。研制挤压油膜阻尼器时,应用此二图,可以带来很大的方便。

关 键 词:挤压油膜轴承  阻尼器  参数分析  燃气涡轮发动机  最优设计

Abstract:If the squeeze film damper is not designed properly, that will be caused the failure of attenuating vibration. This paper has established a bistable region diagram and a boundary diagram of the failure to attenuating vibration.Only the values of bearing parameter B and the unbalance eccentrisity U are not selected in that region, the bistable character will not be arised. B and U are selected to leave that boundaries, also the failure of attenuating vibration will not be happened. To use the two diagrams that will bring a lot of convenience for development of the squeeze film damper.
Keywords:Squeeze film bearing  Damper  Parametric analysis  Gas turbine engine  Optimun design
