The one-dimensional (1D) linear location technique has been considered as one of the methods for determining position acoustic emission (AE) sources in metallic objects. However, this approach does not take into account heterogeneity materials and that leads to poor accuracy AE localization. To estimate positioning error which is typically used determine source a new based on combination experimental simulation proposed. This estimation contains finite element model construction signals...
The article discusses the results of using a standard algorithm for linearly locating sources acoustic emission signals generated by broadband (AE) transducer mounted on surface steel plate with sizes 1000×650×7 mm. To generate AE impulses an amplitude um = 55–100 dB, electronic simulator’s difference potentials was varied in range 10–300 V. As result laboratory experiments, reduced error γ linear location calculated. maximum equal to 16.3% recorded at coordinate X 100 mm source less than 60...
The work is devoted to the study of accuracy standard algorithm for linear location acoustic emission (AE) sources. To solve this problem, a series experimental studies was carried out, consisting in generation signals various amplitudes using an electronic simulator installed on surface steel sample with size 500x50x3 mm. In process processing registered signals, correlation dependences between error and parameters recorded AE pulses were determined. data out digita l signal statistical...
