在影响系数动平衡方。法中，校正的关键在于振动幅值和相位的准确提取。为了达到更好的动平衡效果，在传统的互相关函数法提取振动信号幅值和相位的基础上，利用3σ统计处理方法，对互相关函数法进行改进，更准确的提取出了振动信号的幅值和相位信息。用改进的方法进行刚性转子影响系数双面动平衡实验，达到了很好的平衡效果。
In dynamic balance based on influent coefficient,the key to get a good effect is how to get the amplitude and phase accurately. To get better effect on dynamic balance,some improvements are made based on traditional cross-correlation function by 3σ statistical processing method,so the amplitude and phase can be gotten more accurately. Used the improved cross-correlation function to make the experiment of dynamic balancing of rigid rotors,perfect effect is obtained.
