| 摘 要： | 曲率模态在结构损伤识别中有很好的应用。针对模态分析中某几阶曲率模态曲线未能有效地反映损伤的情况,本文提出对曲线进行一次数值微分的处理方法,计算结果表明这种方法能进一步提高曲率模态对损伤的敏感性,是一种很好的辅助处理数据方法。

| Abstract: | Curvature mode is an excellent parameter in damage identification of structures.While in case that certain curvature mode curve can't show existence of damage,an improved method of curvature mode curve is provided in this paper,that is processed by numerical differentiation.The result indicates that this method can improve the damage sensitivity of curvature mode. |
