摘要
给出了兰姆波的原始特征方程式,以相速度为自变量,求解兰姆波特征方程。通过Matlab软件对求解过程进行编程,绘制出兰姆波在钢板中传播的频散曲线,以此作为进行无损检测的重要依据。
Lamb wave characteristic equation was given. In order to find the zero point of Lamb wave characteristic equation, the phase velocity was be treated as the independently variable. The algorithm was realized with Matlab, and the frequency dispersion curves of Lamb wave propagating in steel were plotted. It is of significance for practical application of Lamb waves in engineering.
