| 摘要: | 为准确检测桥梁缆索等结构内部的钢绞线损伤状况, 采用超声导波检测技术对钢绞线不同损伤程度、位置和断丝根数的工况进行试验. 首先建立损伤程度与导波特征关系, 通过反射系数C定量分析损伤程度, 并结合超声导波传播路径确定损伤位置; 其次基于傅里叶变换的频谱分析确定损伤类型; 最后通过有限元模拟验证超声导波传播路径以及判断损伤程度与位置. 结果表明: 随着损伤程度的增加, 反射系数C呈非线性增长趋势, 且损伤位置在中点对称下靠近接收端的左侧反射系数更大; 通过频谱分析发现磨损损伤的相对系数γ高于70%, 而断丝损伤则低于55%; 有限元模拟与试验得到的导波规律基本一致. |
| Abstract: | In order to accurately detect the damage condition of steel strand inside bridge cables and other structures, ultrasonic guided wave detection technology is used to test the working conditions of the strand with different damage degree, location and number of broken wires. Firstly, the relationship between damage degree and guided wave characteristics is established, the damage degree is quantitatively analyzed by reflection coefficient C, and the damage location is determined by combining it with the ultrasonic guided wave propagation path. Secondly, the damage type is determined by spectral analysis based on Fourier transform. Finally, the ultrasonic guided wave propagation path and the method of determining damage degree and location are verified by finite element simulation. The results show that, with the increasing of damage degree, the reflection coefficient C shows a nonlinear growth trend, and it is more reflective when the damage location is at the left side near the receiving end under the midpoint symmetry; the relative coefficient γ of the abrasion damage is found to be higher than 70% through the spectral analysis, whereas that of the broken filament damage is lower than 55%; the finite element simulation result basically agrees with the guided wave law obtained from the experiment. |
