分析了轴流压气机叶轮偏心旋转时引起失稳力的机理、计算方法、转子失稳特性及稳定性边界等。结果表明，压气机叶轮偏心旋转引起的自激力是推动转子反进动的，因而可造成压气机转子反进动失稳。失稳是在一阶临界转速以上发生，其特征是除有转速频率的振动外，出现一阶反同步进动固有频率的振动，合成非协调进动。失稳门坎值取决于叶轮的负荷和转速。 The mechanism, calculation method, rotor instability characteristic and stability boundary caused by the axial rotation of the axial compressor impeller are analyzed. The results show that the self-excitation caused by the eccentric rotation of the impeller of the compressor impels the anti-precession of the rotor and thus can cause the anti-precession of the compressor rotor. Instability is above the first critical speed, which is characterized by a first-order, anti-synchronous natural frequency vibration of the precession, in addition to the vibration of the rotational frequency, and a non-coordinated precession. The threshold of instability depends on the load and speed of the impeller.
