Abstract
Wave-guiding rod is an auxiliary detection tool of acoustic emission (AE) testing under special conditions and plays the role of transmitting AE signals. But the AE signals propagating in the wave-guiding rod will produce attenuation, which will affect the test result. In response to this problem, according to the theory of stress wave propagation in the wave-guiding rod, we adopted the ABAQUS software and set up a numerical model of wave-guiding properties to simulate the influences of wave-guiding rod to stress characteristics. The wave-guiding rods are designed in different lengths, diameters, and boss types. By comparing the simulation results, we draw the conclusion that wave-guiding rods of 6 mm in diameter, no more than 0.5 m in length with a plate-shaped boss type, will have the minimum attenuation and basically have no impact on the strength of AE signals.
