摘要
研究了转子在工作转速下实现在线自动平衡的方法。以电磁执行器作为施力装置,运用傅里叶分析和线性系统的叠加原理,对不停车的情况下转子不平衡振动的识别和抑制的算法进行了推导,并在一滚珠轴承支承的转子系统上进行了试验研究。结果证明该方法和装置能够使旋转工作频率下转子的不平衡振动大大减小。
The automatic real time balancing of rotor at working speed by active magnetic actuator is studied The algorithm of on line automatic identification and attenuation for unbalance vibration are deduced The method presented is applied in a rotor system supported by ball bearings The experiment results confirm that the unbalancing vibration of rotor in working rotational frequence is greatly extenuated by using above method and device
