METHOD OF INCREASING ACCURACY OF LOCATING NOISE-LIKE SOURCES OF ACOUSTIC EMISSION BASED ON SPECTRAL-TIME SELF-SIMILARITY |
| 摘要 |
FIELD: physics.SUBSTANCE: in order to pick up acoustic emission signals belonging to one event, similarity of spectral density curves of the signals are analysed collectively while comparing time functions of their onset.EFFECT: high accuracy of determining coordinates of noise-like sources of acoustic emission.2 cl, 5 dwg |
