| 基于Ritec-SNAP系统建立了兰姆波实验系统,分析了用兰姆波幅频特性定征固体板表面性质的可行性。实验结果表明,用高阶、多模兰姆波的幅频特性可准确定征固体板表面性质的变化。 |
| 英文摘要: |
| On the basis of Ritec-Snap measurement system, the experimental set-up using a Lamb wave approach has been established. This paper analyzes the feasibility of using the amplitude-frequency characteristics of Lamb waves to characterize the surfaces of solid plates. The experimental results show that the amplitude-frequency characteristics of high-order, multimode Lamb waves can be used to effectively characterize the changes in properties of surfaces of solid plates. |
