METHOD OF DETERMINING COORDINATES OF ACOUSTIC EMISSION SOURCES IN PLANAR LOCATION Russian patent published in 2024 - IPC G01N29/14

Abstract RU 2830422 C1

FIELD: measuring.

SUBSTANCE: invention can be used to determine coordinates of acoustic emission sources during planar location. Essence of the invention consists in the fact that the values of the recording time of acoustic signals are specified by the antenna array transducers t₁'=t₁+Δt₁, t₂^'=t₂+Δt₂, t₃^'=t₃+Δt₃ and design speed υ_g(u_m), normalized relative to velocity of longitudinal wave (c) in the controlled object, using coefficients of regression models A₁…A₄, B₁...B₄, C₁…C₄ in formulas of corrections, based on which coordinates of acoustic emission sources are determined.

EFFECT: reduced error and increased accuracy of location of acoustic emission sources.
