摘要
在对高速回转系统进行平衡措施以减少振动量的研究中,结合电磁式间接在线动平衡头和电磁式在线混合动平衡头的优点,开发一种节能的高速转子在线动平衡补偿装置;利用电磁场的耦合作用,无接触地在加重平面处形成与所需离心力等效的旋转电磁力,实现在线实时精密补偿;并运用影响系数法控制策略,利用旋转极坐标合成矢量力,使转子质心落回旋转中心;同时,时空旋转电磁力消失,转子系统在极坐标合成力的作用下实现最终动平衡。
This paper covers study of some measures to be taken to realize rotor system dynamic balance and thus reduce vibration. An energy - saving high speed rotor on - line dynamic balancing compensation device is developed, which incorporates electromagnetic indirect and hybrid on - line dynamic balancing heads＇ advantages. Electromagnetic field coupling function is applied to form desired radial force to realize precise compensation on weight - added plane. Also, influ- ence coefficient control strategy method is adopted to make rotor barycenter back to rotation center. Thus, the rotor＇s dynamic balance is realized t^nally with the resultant force in revolving polar coordinate while rotating electromagnetic force is vanished.
