模态分析的损伤诊断在桅杆结构中的应用

The application of modal analysis in damage detection of mast

研究了桅杆结构的破坏原因和破坏机理,针对桅杆结构本身的结构动力特性和损伤后的动力特性改变,对应用模态分析方法在桅杆结构的损伤诊断的应用问题进行了分析,指出了模态分析的损伤诊断方法在桅杆结构中的应用方向。

The reasons and mechanism caused the failure of mast are studied. According to structural dynamic features of mast structure and the change of dynamic properties after damage modal analysis is applied for damage detection. In the end the development direction of the application of modal analysis in damage detection is pointed out.
