摘　　要：本文利用激光位移传感器,在线采集砂轮基体外圆表面的振动信号,通过对信号的处理分析,得出砂轮基体的跳动值。在相同转速不同不平衡量的条件下,分析了砂轮基体的跳动值,结果表明:砂轮基体的跳动值随着不平衡量的增大而增大;在相同转速、相同不平衡量下,45#钢砂轮基体的跳动值比铝砂轮基体的跳动值平均约大0.05μm。The vibration signals of grinding wheel substrate were acquired on-line with laser displacement sensor.The run-out values of grinding wheel substrate were obtained by analyzing and processing the vibration signals.The run-out values of grinding wheel substrate with different unbalance were analyzed at the same rotating speed.The experimental results showed that the run-out values increased with the increase of the unbalance of the wheel substrate.The run-out value of 45# steel substrate was 0.05 μm bigger than that of aluminum substrate with the same dynamic unbalance at the same rotating speed.
