针对转子试验台，建立了不同类型润滑轴承下的转子-轴承系统模型，研究了转子系统的动力学特性，分析了不同轴承关键参数下的动刚度和阻尼系数，通过比较，讨论了不同轴承参数下的动支承特性，考虑不同基础支承刚度，分析了不同基础支承刚度下的转子-轴承系统的动力学特性。还研究了转子-轴承系统的临界转速。
Aiming at the rotor test rig,the rotor-bearing system is modeled for different types of lubrication bearings,the dynamical behaviors of the rotor system are then investigated.The dynamical stiffness and damping coefficients for different bearing key parameters are also studied.Via comparison,the dynamical supporting characteristics under different bearing parameters are discussed.With consideration of the different foundation support stiffness,the critical speeds of the rotor-bearing system are also investigated.
