The dispersion curve of Lamb wave is an important basis for non-destructive testing of ultrasonic Lamb wave. In this program, Rayleigh 2Lamb equation is analyzed, and the numerical calculation method of Lamb wave dispersion curve in infinite plate is given. The solving process is programmed by MATLAB software, and the phase velocity and group velocity curves of Lamb wave propagating in aluminum plate are plotted. The non-destructive testing of popularizing Lamb wave is carried out through experiments. The measurement is of practical significance.
