Accurate modal parameters are needed for effective structural damage detection. Here,the NExT-ERA for modal identification in time domain was used to identify high-accuracy modes from noisy structural ambient dynamic responses of limited recording length and time intervals.
为进行结构损伤识别,用时域模态识别的NExT-ERA法,从脉动激励和测量噪声下有限时长和时间间隔的结构反应中提取高精度模态参数。
