| 摘 要： | 基于振动学及有限元理论,推导出结构的频率平方的变化比为结构损伤位置的函数。以一光轴为例,先建立光轴裂纹数据库。然后再把测得的数据与数据库对比,相似性最高的为裂纹的位置所在,从而对损伤的位置进行了识别。最后,提出一些建议和有待解决的问题。

| Abstract: | Square ratio of variable frequency is deduced as the function of structural damage localization by vibration and finite element method. Taking a smooth shaft as an example, database on crack is founded firstly. Compared with the databases, measured data which is the most similar with databases represents the location of crack, and the damage location is identification. Finally, it gives some available advice and irresoluble problem. |
