| 摘 要： | 齿轮出现故障时,在振动信号频谱图中出现形式各异的调制边频带,其中包含有丰富的齿轮故障信息,对边频带进行分析,必须有足够高的频率分辫率.搭建齿轮故障诊断试验台,基于LABVIEW的虚拟仪器平台建立数据采集系统.将基于复解析带通滤波器的ZOOMFFT法应用到故障齿轮振动信号的边频带分析.实验证明,该法提高了频谱分析的频率分辨率,便于准确提取边频带信息,进行故障诊断.

| Abstract: | When the gear fault,side-frequency bands in different shape and size appears in the vibration signal spectrogram,it contains rich gear fault informations.the frequency resolution must be high enough to analyse the side-frequency bands.Build the gear fault diagnosis test-bed,a data acquisition system was designed on the basis of Labview.The method of multiple modulation zoom spectrum analysis based on multiple analytical band-passed filter applys to the side-frequency bands analysis of the vibration signals ... |
