Rapid positioning test method for cylindrical structure penetration based on machine learning

Abstract Focusing on the requirements of rapid damage location test for multi-layer steel plates penetration cylindrical structure in complex and harsh environment, this paper studies propagation characteristics high-speed impact stress waves plates. Also, measurement effects near zone hole are compared with different sensors, so as to select appropriate PZT sensors measure velocity wave actual Then array layout scheme is designed, corresponding algorithm determined. Finally, deep learning used improve accuracy efficiency location.
