自适应除噪技术在滚动轴承故障诊断中的应用

The Appliaction of Adaptive Noise Cancelling Technique to the Failure Diagnosis of Rolling Bearings

本文在阐明自适应除噪技术原理基础上,论述了将此技术应用于带式输送机滚动轴承故障诊断的具体方法和诊断结果分析,证明此技术对于提高信噪比和突出轴承故障特征是一个实用有效的途径。

On the basis of exposition of ANCT, the paper introduces its particular application to the failure di agnosis of rolling bearing. The result shows that ANCT can, in an effective way, raise the signal-to-noise ratio and bring about the prominence of the features of failure.
