Современные акустико-эмиссионные диагностические системы и комплексы являются чувствительным инструментом обнаружения развивающихся дефектов при мониторинге технического состояния объектов в условиях эксплуатационных нагрузок на ранних стадиях. Существенное ограничение применения метода акустической эмиссии – сложность выделения сигналов на фоне акустических и электромагнитных помех. Влияние помех при регистрации акустической эмиссии существенно затрудняет интерпретацию ее параметров, характеризующих техническое состояние объекта контроля. Для повышения значения величины сигнал/помеха и достоверности полученных результатов контроля при количественной оценке параметров эмиссии используют методы фильтрации. Рассмотрено влияние величины сигнал/помеха на погрешность измерения параметров акустической эмиссии, выработанных при компенсации помех с помощью полиномиального метода фильтрации.</p></sec><sec><title>Метод</title><p>Метод. В основу статистической модели определения влияния величины сигнал/помеха на погрешность измерения параметров акустической эмиссии положен метод машинного обучения – линейной регрессии.

Выявлено, что при применении фильтра Баттерворта величина относительной погрешности измерений параметров акустической эмиссии не превышает 3 %, что на порядки ниже значений, полученных для фильтра Бесселя и вейвлет-фильтра на основе материнской функции Добеши 8-го порядка. Установлена высокая обратная не случайная корреляционная связь (r &gt; 0,9), обусловленная снижением значений относительной погрешности измерений параметров эмиссии и повышением величины сигнал/помеха. Разработанная статистическая модель описывает влияние величины сигнал/помеха на значение относительной погрешности при оценке параметров акустической эмиссии. Функционирование предложенной модели подтверждено вычислением коэффициента детерминации и проверки его статистической значимости. Практическая значимость. Показано, что применение фильтра Баттерворта для компенсации помех существенно повышает информативность результатов измерений параметров акустической эмиссии. Разработанная статистическая модель может быть использована при создании новых или усовершенствовании существующих диагностических комплексов и систем обработки данных для повышения достоверности результатов акустического контроля.</p></sec></abstract><trans-abstract xml:lang="en"><p>Modern acoustic emission diagnostic systems and complexes are a sensitive tool for detecting developing defects at an early stage when monitoring the technical condition of objects under operational loads. A significant limitation of the application acoustic emission method is the difficulty in isolating signals against the background of acoustic and electromagnetic interference. The effect of interference during acoustic emission recording significantly complicates the interpretation of parameters that characterize the technical condition of the test object. To increase the value signalto-noise ratio and increase the reliability of the results of acoustic emission testing in the quantitative assessment of parameters, filtering methods are used. The subject of this study is the study of the effect of signal-to-noise ratio value on the measurement error acoustic emission parameters formatted during noise compensation using the polynomial filtering method. The basis of the statistical model characterizing the effect of signal-to-noise ratio value on the measurement error acoustic emission parameters is based on the machine learning method – linear regression. The dependence of the measurement error on the signal-to-noise ratio value was approximated by the least-squares method and visualized using a scattergram. It was found that when using the Butterworth filter, the relative measurement error acoustic emission parameters do not exceed 3 %, which are orders of magnitude lower than the values obtained for the Bessel filter and Daubechies mother functions 8 based on wavelet filter. A high inverse non-random correlation was established (r &gt; 0.9), due to a decrease in the values of the relative measurement error emission parameters and an increase in the signal-to-noise ratio value. The developed statistical model describes the effect of the signal-to-noise ratio value on the value relative error in estimating the acoustic emission parameters. The adequacy of the developed model was confirmed by calculating the coefficient of determination and checking its statistical significance. It is shown that the use of Butterworth filter to compensate for interference significantly increases the information content of the results of measurements of acoustic emission parameters. The developed statistical model can be used in the development of new or improvement of existing complexes and systems for processing acoustic emission data to improve the reliability of the results of acoustic testing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>статистическая обработка</kwd><kwd>повышение точности измерения</kwd><kwd>акустическая эмиссия</kwd><kwd>величина сигнал/помеха</kwd><kwd>акустический контроль</kwd><kwd>помехи</kwd><kwd>фильтр Баттерворта</kwd><kwd>вейвлет-фильтр</kwd><kwd>фильтр Бесселя</kwd></kwd-group><kwd-group xml:lang="en"><kwd>statistical processing</kwd><kwd>measurement accuracy improvement</kwd><kwd>acoustic emission</kwd><kwd>signal-to-noise ratio</kwd><kwd>non-destructive testing</kwd><kwd>noise</kwd><kwd>Butterworth filter</kwd><kwd>wavelet filter</kwd><kwd>Bessel filter</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">He Y., Li M., Meng Z., Chen S., Huang S., Hu Y., Zou X.
