含浮环式挤压油膜阻尼器转子系统的突加不平衡响应分析
|
摘要
为了研究含浮环式挤压油膜阻尼器对转子系统突加不平衡响应的抑制作用,建立了浮环式挤压油膜阻尼器-转子系统的动力学模型,在模型中,充分考虑了转子与浮环式挤压油膜阻尼器的耦合作用.运用数值积分获取系统的动力学响应.研究表明,与传统挤压油膜阻尼器相比,浮环式挤压油膜阻尼器能更好地抑制转子系统的突加不平衡响应;在靠近临界转速时,浮环式挤压油膜阻尼器能抑制瞬态过程;较大的浮环质量和滑油黏度能更好地抑制转子系统突加不平衡响应.
To research the prevention of sudden unbalance response of rotor system supported on floating-ring squeeze film damper(FSFD),a dynamic model of the rotor supported on FSFD was established.In the model,the coupling effect between rotor and FSFD was considered.An efficient numerical integration approach was employed to conduct the investigation into the dynamic response of rotor.The main results are as follow:compared with traditional squeeze film damper,FSFD has better performance in preventing both sudden unbalance response of rotor and transient process when the rotor speed approaches the critical speed;the greater mass of floating ring or viscosity of lubrication oil means better performance of FSFD in preventing sudden unbalance response.
