The Simulation Research for Defect in Pipes Based on Time Reversal Ultrasonic Guided Wave

Abstract:

According to the insufficient ability of the existing ultrasonic guided wave detection technique, proposed a method for small defects in pipes based on time reversal (TR) ultrasonic guided wave. The L(0,2) mode guided waves was encouraged in the simulation research experiment. Results show that the guided wave detection signal has linear superposition properties, realized the detection energy focus on the location of the defects, and improved the ability of detection for small defects. The experiment lay a foundation for the miniaturization of the detection equipment.
