Abstract

Guns, especially new type guns play an important role in modern warfare. As an important part of gun, the barrels’ damage detection is of great significance. After studying and comparing the characteristics of L mode and T mode ultrasonic guided waves, this paper puts forward a nondestructive detection method based on L(0,2) mode guided wave. By using finite element software—Comsol, this paper simulates the guided wave propagation characteristics when asymmetric defects exist on the inner surface of gun barrel. The research and simulation results indicate that this method can be used to recognize guided wave mode and detect defects. It is hoped that this paper can provide some instructions to future researches on barrel detection.
