Method to Detect Bolting Devices Based on Ultrasonic Guided Wave

摘要

Bolting devices is very popular in industrial application, this paper presents a new aimed at the problem faced in detecting the construction quality.The solution is based on the engineering practice, and we introduce Ultrasonic Guided Wave NDT technology in the detecting process.Under laboratory conditions, Longitudinal Guided Waves are used in detecting the devices, the experimental results are consistent with the theoretical analysis.At the same time, finite element method is applied into the Numerical Simulation of the propagation of Longitudinal Waves in bolts, thus a test system utilized in detecting the effective length and defects of bolts developed.
