| 应用三维弹性理论对Lamb波频散曲线进行理论建模.在Lamb波主动监测系统中,应用Gabor小波变换理论分析Lamb波信号的时延及相位角,获得了板中Lamb波的相群速度频散曲线.比较理论曲线与实验数据,证明了三维弹性理论建模方法的有效性. |
| 英文摘要: |
| In this paper,the frequency dispersive curves of the Lamb waves propagating in plates are modeled using the 3-D elastic theory.In the experiments,according to the time delay and the angle of Lamb wave signals analysed by Gabor wavelet transform,the experimental dispersive curves are obtained.Compared the two dispersive curves,the 3-D elastic theory could be proved efficient. |
