| 摘 要： | 基于匹配追踪算法的去噪方法既可以实现有效去噪,又不会损伤有效波,而且不需要先验获知信号的统计特性,在故障诊断领域发挥着重大作用.文中开发了一套轴承故障诊断系统.该系统是在LabVIEW8.6.1平台上开发的,包括数据采集模块、历史数据查询模块、原始信号分析模块、匹配追踪算法实现模块、生成报表模块.系统先用Microsoft Access创建数据库,再用库函数NI - DAQmx编程进行数据采集,然后用Database Connectivity工具包编程存储和查询数据,最后用MathScript节点编程,实现匹配追踪算法的应用.利用该系统对轴承进行故障诊断,诊断结果更加可靠、有效.

| Abstract: | A denoising method based on matching pursuit(MP)can denoise successfully,and will not damage the significant wave of the signal,and need not foreknow the statistical properties of the signal,so it has an important value on the fault diagnosis field.A fault diagnosis system of rolling bearing based on virtual instrument and MP was designed.The system was developed under the platform of LabVIEW8.6.1,it included data acquisition module,history data query module,analysis of the original signal model,MP model,an... |
