摘 要: 研究了一类电磁轴承转子系统在1∶2内共振情形下的全局动力学行为.用数值仿真验证了理论的正确性.其分析结果对抑制转子系统的内共振运动有重要意义. The internal resonance is studied by adopting the method of multiple scales and the normal form theory,and the global bifurcation dynamics of the system are obtained.This precedes a new theoretical basis in protecting the rotor from the resonant failures in the turbine machinery.
