摘　　要：透平压缩机的亚异步振动失稳,对机器危害很大。为解决这类问题,文中利用挤压油膜阻尼器来提高转子的稳定性,并提出了一种优化设计方法。最后通过实验验证了本方法的有效性。The nonsynchronous vibration is dangerous to large turboeompressor.A method was described for solving this sort of problems.The stability of rotor system will been improved by used squeeze film damper and its optimal design method was also described.The availability has been proved by experiment.
