摘要: 为了消除诸如微型轴承噪声测试分析中存在的强大背景噪声问题,本文引入了一种新的 信号处理方法--自适应消噪技术ANC(Adaptive Noise Cancelling).实践结果表明,自适 应消噪技术是一种能很好地消除背景噪声影响的信号处理技术,它为轴承噪声等动态信号的 现场测试分析和机械故障诊断提供了有效的方法和依据.Abstract: In order to cancell the influence of the enormous background noise, this paper introduces a new kind of signal processing method the Adaptive Noise Cancelling technique (abbreviated as ANC). The practical result indicates that ANC can cancell the background noise effectively. It offers effective method and basis not only for on-the-spot measuring and analysis of bearing noise or other dynamic signals but also for mechanical fault diagnosis.
