摘要
由于基础承受垂向冲击时,磁悬浮转子系统的转子与定子极易碰撞,重点研究垂向冲击激励下磁悬浮转子系统的响应特性。通过龙格库塔法,计算磁悬浮转子系统的冲击响应,并分析冲击激励和不平衡力波动对响应特性的影响。结果表明,冲击脉宽和转速对响应幅值增大的速度有显著影响。
This paper considers that the rotor and stator in the magnetic suspension rotor system can easily collide when the foundation is subjected to vertical impact,so it focuses its attention on a study of its response characteristics under vertical impact excitation.The impact response of this system is calculated by Runge-kutta method,and the influence of impact excitation and unbalance force fluctuation on its response characteristics is analyzed.The results show that pulse width and rotation speed have a significant effect on the response amplitude.
