| 摘要: |
| 用精细时程积分法求得响应的进程，进行傅里叶变换后，预频率响应峰值对应的频率，得到了结构的固有频率。本文中介绍的方法，对结构的阻尼不做要求，相对普通的迭代法计算更简单、迅速。 |

| Solution of Natural Frequency of Structures Using Precise Time integration Method |
|
|
|
| Abstract: |
| Course of response is obtained by using precise time integration method; after Fourier transform, the frequency which is opposite to peak value of frequency response is natural frequency of structures. By using the proposed method, it is simple and quick to obtain the accurate results with no restriction to damp. |
| Key words: precise time integration method,natural frequency,Fourier transform |
