基于谱图的桅杆结构杆件损伤识别
首发时间:2007-05-04
摘要:桅杆结构是一种高柔结构,具有非常强的非线性,运用频域法对其损伤进行识别非常困难。本文运用谱图的时频分布一阶频率矩的方法,对有杆件损伤的桅杆结构进行了分析,并找到损伤弦杆的位置。

Damage Detection of Mast Structural Bars Based on Spectrogram
Abstract:The mast structure is a kind of high-slender structure, it is difficult to detect the damage with the method based on frequency range. this article applys the time-frequency distribution analysis method based on spectrogram to analyse a damaged mast,and find the position of damged bars.
Keywords: mast structural bars, damage detection, time-frequency distribution analysis,spectrogram
