摘要 针对仅考虑质量偏心的Jeffcott转子碰摩的动力学方程 ,进行了转子碰摩系统的灵敏度分析 ,研究了转轴刚度和阻尼、偏心距和定子的刚度对灵敏度的影响 ,并给出了数值分析解 ;讨论了参数的变化对碰摩的产生和影响 。 On the basis of the impact rub dynamics equation of Jeffcott rotor with imbalance,the sensitivity analysis of rotor systems with impact rub is studied.The effect to sensitivity of parameters of shaft stiffness,external damping coefficient,imbalance interval and stator stiffness is considered and discussed.The numerical results are obtained.The blindness in the rotor design is prevented.
