Description
жений свободного перемещени преобразовател по шероховатым поверхност м контролируемых изделий и уменьшени вли ни контактной гибкости.the free movement of the transducer over the rough surfaces of the products being monitored and reducing the effects of contact flexibility.
Предлагаемый преобразователь работает следующим образом.The proposed Converter works as follows.
Излучающий вибратор через контактный наконечник возбуждает в контролируемом изделии упругие колебани . Их амплитуда тем больше, чем меньше модуль механического импеданса издели в зоне его возбуждени . Дефект уменьшаетс , что сопровождаетс увеличением амплитуды колебаний по сравнению с бездефектными зонами издели . Поэтому, когда оба вибратора наход тс в зоне дефекта, последний отмечаетс по увеличению амплитуды сигнала на выходе приемного вибратора .A radiating vibrator through a contact tip excites elastic oscillations in a controlled product. Their amplitude is greater, the smaller the modulus of the mechanical impedance of the product in the area of its excitation. The defect is reduced, which is accompanied by an increase in the amplitude of oscillations compared with defect-free areas of the product. Therefore, when both vibrators are in the defect zone, the latter is noted by an increase in the amplitude of the signal at the output of the receiving vibrator.
Предлагаемый преобразователь позвол ет сблизить точки касани вибраторов с контролируемым изделием, благодар чему обладает повышеннойThe proposed converter allows to bring together the points of contact of the vibrators with the controlled product, due to which it possesses enhanced
увствительностью по сравнению с римен вшимис ранее. .sensitivity compared to impregnated vimys earlier. .
