摘　　要：振动信号是反映精密球体研磨状态的重要途径。利用加速度计传感器、数据采集卡和LabVIEW,设计一套基于虚拟仪器的振动信号检测设备,对精密球在研磨加工过程中的振动信号进行测试,从时域、频域等多个角度进行分析。结果表明:利用精密球体研磨加工的振动信号能有效地监控整个研磨过程,实时反映球体研磨的状态和精度。Vibration signal is one important approach which can reflect the state of ball lapping. The grinding vibration signals in the process of precision balls grinding were tested by one detection device built by data acquisition kard, accelerometer sensor and virtual instrument software. These signals were analyzed from time domain and frequency domain. The results indicate that grinding vibration signals can be used to monitor the process of ball grinding. The grinding state and precision of precision balls can be reflected realtime.
