综合传动装置齿轮故障诊断研究

Research on Gear Fault Diagnosis of Integrated Transmission

介绍了基于Morlet组合小波的频谱细化与解调方法的基本原理。将两种方法相结合,先进行细化分析观察频谱细微结构,再进行解调分析提取故障特征频率。实践表明,该方法能够有效地诊断出综合传动装置齿轮调制性故障。

Basic principle of spectrum zooming and demodulating methods based on Morlet combined wavelets are introduced.Combining the two methods together,the detailed structure of spectrum by using zooming method is observed,and then the characteristic frequency of fault by using demodulating method is extracted.Practice shows that,this method can effectively diagnose the demodulating fault of integrated transmission gear.
