Аннотация

The paper presents the results of laboratory experiments and numerical modeling for solving the problem of acoustic emission event recovery. The equations of the dynamic theory of elasticity in the polar coordinate system were used as a mathematical model. For reconstructing acoustic emission events Time Reverse Mirror approach with total energy imaging was used. The simulation results made it possible to evaluate a number of basic characteristics for the configuration of a multichannel data acquisition system, the frequency of the acoustic emission signals, to determine the required number of recording channels and the position of the sensors in the core.
