| 摘 要： | 针对非线性磁浮轴承转子系统的特点,建立了刚性磁浮轴承转子系统的非线性动力学方程。运用多尺度法研究了系统主参激共振的一次、二次近似稳态响应。结果表明,二次非线性项对系统稳定性有重要影响。为更好控制磁浮轴承转子系统运行状态提供了理论参考。

| Abstract: | The nonlinear dynamic equation of a rigid magnetic rotorbearing system is set up.The first order and second order approximations for steady state responses of the system under principal resonance are investigated with the multi-scale method.The result indicates that the second order nonlinear items affect the steady state frequency response of the system obviously.The conculsion offers a reference for controling a magnetic rotor-bearing system. |
