| 摘 要： | 基于正则化频率变化率仅与损伤位置有关的理论,建立了多阶频率与损伤位置的关系图,并以新政航电泄洪闸门为例进行了损伤识别。结果表明,该方法进行损伤位置识别精度较高,且能定位到具体的损伤单元。

| Abstract: | Based on the conclusion that regularization frequency variation is only related with damage position, we establish the relationship diagram between multi-order frequency and damage position. As an example, we try to recognize the discharge gate damage of Xinzhenghangdian. The results show that damage location identification is accuracy even accurate to the specific damage elements. |
