同态滤波技术应用于皮带机轴承故障诊断的试验研究

Experimental Research of Applying the Homomorphic Filtering Technique to Failure Diagnosis of Bearing in Belt Conveyers

在试验的基础上，本文提出了把同态滤波技术用于皮带机（带式输送机）滚动轴承故障诊断的方法。试验分析结果表明，同态滤波技术是一种提高轴承信号信噪比的行之有效的方法，通过同态滤波技术处理之后，使轴承的故障特征更为明显．

Basing on the Experiment, this paper exposes the method applying the homomorphicfiltering technique to the failure diagnosis of bearing in belt conveyers. The analysis of theexperimental results proves that the homomorphic filtering technique is a practical andeffective method to raise the signal-to-noise ratio, After using the technique, the failurecharacteristics become more outstanding.
