摘要
首先在介绍旋转机械故障振动信号的时域、频域和时频域分析的基础上,简单介绍了单一智能故障诊断技术,其次详细介绍了混合智能故障诊断技术的一些典型应用,最后指出了智能故障诊断领域中有待进一步研究的若干问题和发展趋势。
Firstly,the vibration fault singles of the rotating machinery is analyzed using the methods of time-domain,frequency-do- main and time-frequency domain,and the actuality of single intelligent fault diagnosis technology is introduced.Secondly,the typical application of the hybrid intelligent fault diagnosis is reviewed.Finally,the problems existing in intelligent fault diagnosis field are also pointed out and the development trends of fault diagnosis are discussed in this paper.
