  • Spectral correlation density analysis on bearing point defect diagnosis
    谱相关密度分析在轴承点蚀故障诊断中的研究
  • The spectral correlation density must be estimated before the ds signal parameter estimation . in order to reduce the effect of random noise, we provide a improved method to estimate the spectral correlation density which is based on the average algorithm . it can make the spectral line be more obvious, and improved the snr limit when estimating these parameters
    在利用ds信号谱相关域所表现的特征进行参数估计时,首先要利用有限时间数据对ds信号进行谱相关密度估计,为降低随机噪声对谱相关密度估计的影响,本文引入了集平均的思想,提出采用集平均的方法估计谱相关密度,从而在参数估计时,特征谱线更显著,提高了参数估计的信噪比容限。
