摘要

摘要: 鉴于挤压油膜阻尼器(SFD)设计必须要同时考虑转子系统的动力学特性,提出了一种转子系统与挤压油膜阻尼器耦合设计方法,给出了详细的设计流程。对所设计的阻尼器进行了CFD数值模拟、油膜压力测量以及减振效果实验,结果证明所提出的设计方法是有效的。相比未采用阻尼器,采用阻尼器后转子系统两个转盘的振幅分别下降了46%和39%。通过实验还研究了不平衡量、支承刚度、供油压力和滑油温度对挤压油膜阻尼器减振效果的影响。结果表明,相比于不平衡量和支承刚度对减振效果的影响,供油压力和滑油温度的影响并不显著。进行挤压油膜阻尼器设计时,重点应该关注转子上的不平衡量大小和支承刚度。

Abstract: Given that the dynamic characteristics of rotor system must be considered during design of squeeze film damper (SFD), a coupling design method of rotor system and SFD was proposed, and the detailed design process was shown. Computational fluid dynamics (CFD) simulation, oil film pressure measurement and vibration reduction experiment were carried out. The results showed that the proposed design method was effective. The amplitude of the two disks on the rotor system decreased by 46% and 39%, respectively, after using SFD. The effects of unbalance, support stiffness, oil supply pressure and oil temperature on the damping effect of SFD were also studied. The results show that the effect of oil supply pressure and oil temperature is not significant compared with that of unbalance and support stiffness. It is important to pay attention to the unbalance and support stiffness when designing SFD.
