摘要
研究设计了一种具有高效减振效果的新型剪切式粘滞性阻尼器,并引入旋转机械中对转子不平衡、不对中、碰摩、油膜涡动等故障引起的振动进行控制研究。建立了转子实验台,应用该剪切粘滞阻尼器实验研究了转子系统在不同转速区由不平衡、不对中、碰摩及油膜涡动引起的振动、其减振效果和阻尼器安装位置对轴系振动的影响。实验结果表明,在不同转速区下,该剪切粘滞阻尼器能明显地降低转子系统由于不同频率故障引起的振动,为在线抑制转子振动提供了新技术。
A new shear viscous damper with the high-damping machinery system for doing the research on control of the function was designed, and was introduced into a rotating vibrations caused by such failures as rotor unbalance, mis- alignment, friction and oil whirl. A rotor test rig was established to experimentally verify the effectiveness of the shear viscous damper on suppression of the rotor system＇ s vibrations caused by the above-mentioned factors in dif- ferent speed zones, and study the influence of the damper＇ s mounting position on the shafting vibration. The experi- mental results show that at different speeds, the viscous shear damper can significantly reduce the rotor vibrations caused by different failures, which can help provide new technologies for online suppression of rotor vibration.
