Abstract Based on the elaboration of the technical principle of ultrasonic guided wave and its application in rail, this paper analyzes the attenuation principle of ultrasonic guided wave and the attenuation types considered in practice. Using the experimental data, comprehensively considering the influence of different attenuation, a more appropriate attenuation function is obtained, which provides guidance for the judgment of the rail damage size and the installation of related ultrasonic guide wave rail detection equipment.
