摘　　要：本文提出一种单向法测量主轴回转精度时,标准球的偏心误差和主轴动不平衡误差的分离与修正方法。该法在消除偏心误差的同时,保留了主轴动不平衡引起的、与主轴旋转频率ω_0相同的振动位移分量,提高了测试精度。且可根据分离出的动不平衡的大小和方向,对主轴进行动平衡调整。In this paper, an error separation and compensation method of the eccentricity in the measurement of spindle rotary precision is introduced. With this method used, the eccentricity can be removed away, but the vibration displacement caused by the dynamic unbalance of spindle is reserved, which has the same frequency as ω0. that the spindle turn with. Therefore, not Only the measuring precision is improved but also the dynamic balance of spindle adjusted accoring to the size and direction of the measured unbalance.
