摘要
充分利用小波和现代谱分析的优点，提出一种新的谱分析方法——高斯小波－最大熵谱分析方法。介绍了该方法的分析步骤，并应用于减速机的故障诊断。该方法实现了在机械设备故障诊断中不同频带范围内零部件故障信息的分离和提取。
The paper takes advantage of wavelet and contemporary spectrum analysis and puts forward a new method called Gauss wavelet MEM spectrum analysis.The steps of analysis are introduced in this paper.Furthermore,applications of the method in the fault diagnosis of reducing gears are given.In fault diagnosis of machinery,the method can extract fault information of machine parts of different frequency bands.
