摘要
以某型具有定心型挤压油膜阻尼器（ＳｑｕｅｅｚｅＦｉｌｍＤａｍｐｅｒ，ＳＦＤ）和锥齿轮啮合的发动机转子系统为对象，研究了定心型ＳＦＤ对发动机转子系统的减振作用，提出了分析ＳＦＤ对发动机减振作用应包含的内容和分析方法。同时，在支承刚度对该机减振效应有影响方面也进行了讨论。
With the object of an engine rotor system containing centralized SFD and bevel gear engaging, the effect of centralized SFD on suppressing engine vibration is studied.The method analysing SFD′s function in reducing engine vibration is set up. It is also discussed in detail that support stiffness has influence on weakening the engine vibration. [WT5”HZ〗
