| 摘 要： | 运用Hilbert-Huang变换对柴油机振动信号进行去噪处理，对去噪处理的结果进行分析．结果表明：利用Hilbert-Huang变换的多尺度滤波特征可以有效地去除信号的噪声干扰，克服了傅里叶变换用高次谐波频率分量拟合非线性、非平稳信号的缺点，从而提高振动信号分析的可靠性．

| Abstract: | Hilbert-Huang Transform is utilized to denoise vibration signals of diesel engine and the denoising results are analyzed.It is found that the multidimensional filtering characteristics of Hilbert-Huang Transform can effectively remove the noise signal and improve the reliability of vibration signals by overcoming the shortcomings of Fourier Transform,which fits nonlinear and nonstationery signals with high-order harmonic frequency component |
