Using wave signatures for identifying mechanical objects

Abstract

The article provides a rationale for identifying objects based on wave signatures. Wave signatures in the article are limited to the acoustic range of vibration. The results of experimental studies based on modeling the dynamic processes of propagation of complex excitations in samples of various configurations and with the presence of various defects using the signature of acoustic oscillations excited in the objects of study are presented. As such objects are presented parts of engineering production. These studies confirm the possibility of complex diagnostics of objects with their subsequent use in product quality control systems, in particular, to reduce the level of peak values of residual stresses in body parts during multi-frequency vibro-processing.
