Hereby, the change ratio of the first order mode shape is presented as the indicator for structure damage detection.

提出以第一阶振型改变率作为结构损伤识别的标识量。

At first the authors, construct a substructure synthesis method that can be used to set up the connection between measurement mode shape parameters and the damaged substructures.

首先，构造一种能建立测量模态参数与损伤子结构之间关系的子结构综合法。
