提出了一种利用计算机实现转子不平衡量相位在线测量的新方法,并在磨床上对砂轮不平衡量相位进行了在线测量试验。设计的系统结构简单,测量精度高。 A new method of on-line measurement of rotor unbalance and its phase was proposed by computer, and the on-line measurement of the unbalanced phase of grinding wheel was carried out on grinding machine. The designed system has simple structure and high measuring accuracy.
