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。
A kind of engine rotor system with centering squeeze film damper (SqueezeFilmDamper, SFD) and bevel gear meshing was studied. The damping effect of centering SFD on the rotor system of the engine was studied. The effect of SFD on engine subtraction Vibration should include content and analytical methods. At the same time, the stiffness of the support stiffness of the impact of the aircraft have also been discussed.
