В процессе работы было рассмотрено современное состояние научных исследований электромагнитного поля дефекта. Наше исследование отличается тем, что электромагнитное поле вызвано за счет неоднородного возбуждения линейным током. Разработан экспериментальный стенд, с помощью которого проводился опыт. Сделано описание работы экспериментального стенда, а также описание таких элементов стенда: металлический образец, датчик и система позиционирования. Приведенные характеристики используемого сигнала. Приведена методика проведения эксперимента. В результате были получены графики распределения электромагнитного поля поверхностного дефекта. Проведен анализ графиков и сделаны выводы.

Ключові слова


поверхностный дефект; электромагнитное поле; вихревой ток; распределение электромагнитного поля; неразрушающий контроль; неоднородное возбуждение линейного тока.
