Simulation Research on Acoustic Emission Signal of Tank Corrosion
This paper studies the cylindrical acoustic emission signal generation, propagation and attenuation. Acoustic emission signal is a form of elastic waves and mechanical waves also. The large finite element physics simulation software COMSOL is used to simulate the propagation of acoustic emission signals coursed by the oil tank bottom corrosion. Simulation is divided into two parts，they are separately two-dimensional simulation and three-dimensional simulation. The bottom part of oil tank is two-dimensional simulation and the entire tank is three-dimensional simulation. Two-dimensional simulation is achieved in different situations. Strength of point source are the same in different positions, and the same point source position has different intensity. Acoustic emission wave propagation has a greater relationship with the media of dissemination, the point source position and the different interfaces.
