摘要 从信号分析的角度 ,引入基追踪降噪 (Basis Pursuit De- Noising)的基本原理。通过对含有白噪声的典型脉冲信号进行降噪处理 ,展示基追踪降噪在脉冲信号特征提取中的优点。最后对变速箱齿轮故障信号进行降噪处理。结果表明 ,该方法可以有效去除强噪声干扰 ,提取脉冲故障特征信号。 Vibration signals are frequently used in mechanical fault diagnosis.However,in many cases,because of very low signal to noise ratio(SNR),it is difficult to detect the fault.In this paper,a de noising method based on Basis Pursuit is introduced.The advantage of the method in extracting impulsive signals buried in noise is revealed by applying it to two simulated impulsive signals with additive white noise.The application of the method to gear fault diagnosis also gets an expected result.
