摘要
波分解能够精细地把信号划分到不同的频带范围内 ,因此可对振动信号在不同频道范围内的特征进行信息分离 ,本文从设备诊断领域特征识别的应用角度 ,探讨了基于小波分解的信噪分离方法 ,并结合具体实例 。
As the wavelet analysis may divide a signal into different nice ranges, the feature composition of vibration signal can be separated distinctly. An approach of signal noises separation based on wavelet analysis is discussed from the angle of equipments diagnosis. Through instances, the validity of wavelet analysis and its practicability in machinery vibration signal processing is demonstrated.
