| 摘 要： | 本文通过对某斜拉桥主塔的模态测试，得到结构在自然激励下的自振频率。再利用ANSYS优化设计功能，对斜拉桥的主塔进行动力有限元模型修正，得到了修正后的设计参数和计算频率,使得有限元模型更加接近于实际结构。

| Abstract: | By modal experiment of a cable-stayed bridge,the structure's natural frequency based on ambient vibration is got.Then using the ANSYS'function of the optimal design,finite element dynamical model updating is made for the tower of the cable-stayed bridge,and gained the improved design parameters and calculated frequency.it made the finite element more close to actual structure. |

| Keywords: | modal experiment natural frequency optimal design finite element model updating |
