Multi-function training bench for study ing the processes of generation and propagation of acous tic emission waves

Abstract

A design and algorithm of using certified multi-function education and research training bench are presented. The design of the bench provides simulation of a wide range of conventionally monitored items (vessels, pipelines, tubular furnaces, tanks, etc.) and main sources of acoustic emission (AE): cracks, leaks, corrosion damage induced by aggressive media, etc. AE simulator devices (AESD) are mounted on the bench via waveguides which provides acoustic communication and safety of the key elements even upon damage of the simulator. AESD are controlled using a loading device which provides setting of the onset and rate of AESD destruction. Design features of the bench also provide a possibility ofrepetitive simulation of a variety of situations that arise in-service and upon technical diagnostics of dangerous industrial objects at minimum costs. The bench can be used in research, training, certification of AE techniques and equipment, and nondestructive laboratory testing.
