| 摘 要： | 在简单介绍WH-800型离心机基本结构及工作原理的基础上，介绍了基于重构吸引子轨迹矩阵的奇异值分解技术，并引入自相关函数对现有奇异值分解技术加以改进．通过对现场实测故障信号的分析，表明改进的奇异值分解技术具有很好的降噪效果，能在强噪声背景环境下准确提取设备的故障特征信号，为离心机的故障诊断提供了一种新的思路．

| Abstract: | The basic configuration and principle of WH-800 centrifuge were introduced.And then we introduced and improved the singular value distribution of the Singularity Value Decomposition about track matrix of attractor reconstructed by time series,which imported the autocorrelation function.The analysis of the test signals shows that the singular value distribution method is very effective in depressing noise and detecting faults of the centrifuge,which offers a new method to the faults diagnosis of the centrifu... |
