悬臂梁结构损伤检测方法研究

Study of damage detection for cantilever beam structures

提出了一种基于模态应变能的损伤诊断指标,并用于悬臂梁结构损伤检测。验证结果表明该损伤诊断指标能够有效地对结构的损伤进行精确定位,对构件损伤程度的评估也能得到令人满意的结果。

This paper presents a damage detection index based on modal strain energy, and applies it into damage detection of cantilever beam structure. The result of the illustration indicates that the damage detection index can locate the damage of structure precisely, and get the satisfied result of the evaluation to the damage extent.
