摘要
以某微型涡轮发动机转子系统为对象,建立了两种不同的有限元模型对转子系统进行了振动性能研究。在考虑轴承径向刚度的基础上,分析了支承刚度对转子系统振动性能的影响。
Based on the rotor system of some micro-turbo, two different finite element modals of rotor system are built and the vibration behaviors of rotor system are analyzed. While considering radial stiffness of bearing, the effect of stiffness coefficient of rotor supporters to vibration behavior of rotor system are researched.
