摘要
研究了适用于梁结构的基于曲率模态理论的损伤识别方法。以一悬臂梁结构有限元模型为数值算例,考虑悬臂梁结构的单构件损伤、多构件损伤等两种损伤工况,分别采用了模态频率、位移振型模态和曲率模态三种指标来进行损伤识别的研究。数值实验分析表明,曲率模态方法能较好地进行损伤定位,并能对损伤程度给出定性的描述。
A damage identification approach applied aptly in beams based on the curvature mode theory is studied in this paper.With a cantilever beam structure finite element model as a numerical example,consider the structure of a single member damage and multi damage,respectively,using the modal frequency,displacement mode shape and curvature modal to study the damage identification.
