基于Qt与Matlab的行星齿轮传动系统故障监测诊断研究

Research on Monitoring and Fault Diagnosis of the Planetary Gear Transmission System by Using Qt and Matlab

以大型风力发电设备中行星齿轮传动系统为研究对象,针对行星齿轮箱故障监测诊断问题,进行了小波包去噪和Hilbert解调技术的理论方法研究,并在Windows平台下运用Qt和Matlab进行了行星齿轮箱故障监测诊断系统开发,最后进行了试验分析。结果表明,系统能够在行星齿轮箱不同工况下,从测试的振动信号中解调出故障齿轮的调制信息,进而判断出故障齿轮的部位,进而实现了系统的故障监测诊断。研究可为行星齿轮传动系统故障诊断提供数据采集与分析技术支持,有利于进一步实现基于网络技术的远程在线监测,具有一定的工程应用价值。

Objected to the planetary gear transmission system in large-scale wind power generation equipment,the research is on the technique about monitoring and faults diagnosis of the planetary gearbox and its application.And the monitoring and fault diagnosis system develop is carried out and continuously competition experimental verification is done.The results showed that With different working conditions,the developed system could be used to online monitoring and fault diagnosis work and further demodulated analysis about modulation information of the faulty gear of the system could be give out.The research could provide data acquisition and analysis technical support for the fault diagnosis of planetary gear transmission system,which is help for the remote online monitoring technique development based on network technology and thus is practically valuable.
