| 摘 要： | 本文提出一种基于相空间再构（ＰＳＲ）的奇异值分解（ＳＶＤ）谐波分析方法，可将信号中的谐 波分量按其能量大小进行时域分解。数字模拟实验表明了该方法的有效性。利用该方法对建筑结构振动进行的隐藏频率提取和谐波分析，对于我们对建筑结构振动的控制方案的设计具有指导作用。

| Abstract: | We introduce a method ,which based on phase space restruction (PSR) and singular value decomposition (SVD), to detect hidden frequencies and harmonic components in stochastic time series. By means of this method, signal is decomposed in time field and each component is ranged by its magnitude. The results of numerical simulation show that the method can work well. It also provides available means to analyse vibration of building for us to control the vibration of structure. |
