| 摘 要： | 本文对高烟囱的随机响应数据进行了模态参数的时域识别,并在此基础上进行了频率公式的拟合。该公式建立了前三阶振动频率与振动阶数的线性关系。与实测结果相比,其相对误差一般在16％以下,有一定的参考价值和实用意义。

| Abstract: | The modal parameters identification in time domain is made with the data of random response of superhigh chimneys. A frequency formula is fitted with the results of the identification. The formula sets up a linear relation of the first three-order frequency to the order of the vibration system. It's relative error is usually less than 16% compared with the trial results. |
