【摘要】 本文以线性项和立方项之和来表示转轴材料的物理非线性因素,建立了具有非线性刚度弹性轴的转子系统的动力学方程,利用多尺度法对系统的非共振、主共振、超谐共振和亚谐共振等非线性动力学响应进行了分析,为具有此类特性的转子系统安全运行提供了理论参考。更多还原

【Abstract】 The dynamic model of the nonlinear rigidity rotor system was set up, taking the linearity and cube item as the physics nonlinear factors. The nonlinear dynamic behaviors were studied about non - resonance, main - resonance, superharmonic resonance, subharmonic resonance, through the method of multiple scales. The conclusions provide theoretic reference for safety run the rotor system.更多还原
