| 摘 要： | 基于应变模态对结构局部特征变化比较敏感和频率指标测试简单方便、精度高的特点,以既能实现准确定位又便于工程应用,以动力响应诊断的应变模态指标为基础,结合频率指标提出了实用的组合指标.理论证明和数值仿真结果表明,无论单处还是多处损伤、低阶还是高阶模态,损伤识别组合指标均能在判断损伤存在的同时准确定位损伤.

| Abstract: | Damage detection indexes have their own characteristic and deficiency. Strain mode is sensitive to structure local characteristic changes and has a great theory foundation. But effect of only using strain mode index is not ideal. As the reaction of structure integral property, structure damage identification index based on frequency can't realize exact locations of damage, though it can be measured conveniently with high precision and widely used in engineering. In order to locate precisely and be applied i... |
