采用虚拟仪器技术原理,提出以LabVIEW为软件,以美国虚拟仪器公司的CompactDAQ数据采集系统和光电传感器为硬件,开发滚动轴承故障检测仿真实验平台,得出轴承振动时域波形图. 通过LabVIEW和Matlab混合编程的方法,在仿真平台上计算出轴承低频有效值、中频有效值、高频有效值、冲击脉冲数、解调有效值因数5个检测参数. 将数据与标准值进行对比,以此判断轴承故障是否存在. 仿真实验结果表明,该系统所测数据与专业振动仪器测试数据高度相似,仿真系统具有一定的实用性和可靠性.

According to the principle of virtual instrument, develops a simulation experiment platform and educes the time-domain waveform of the bearing vibration by using LabVIEWs and the data collection system CompactDAQ by American Virtual Instrument Company as well as the photoelectric sensor.By the mixed programming of LabVIEW and Matlab,five detecting parameters—the virtual values of low frequen-cy,medium frequency,high frequency,number of shock pulses and demodulation effective factors—are cal-culated on the platform and the bearing faults are judged and compared with the standard values.The experi-mental results show that the test data is highly similar to that of the professional vibration instrument and the simulation system is proven practical and reliable.
