摘要
本文分析了为何在应用时域方法识别结构参数时,阻尼系数往往是难以识别精确的,提出了一些提高阻尼系数识别精度的措施。
In this paper, the problem is investgated that why damping coefficients are difficult to be identified accurately by time domain structure parameter identification methods, some suggestions are proposed to improve the identification accuracy of damping coefficients.
