Description
(5) ЭЛЕКТРОМАГНИТНЫЙ СТРУКТУРОСКОП(5) ELECTROMAGNETIC STRUCTURE
1one
Изобретение относитс к неразрушающему контролю и может быть использовано дл контрол структуры электропровод щих ферромагнитных объектов.The invention relates to non-destructive testing and can be used to control the structure of electrically conductive ferromagnetic objects.
Известен электромагнитный структуроскоп , содержащий последовательно соединенные генератор, вихретоковый прес разователь, многоканальный амплитудно-фазовый анализатор гармоник, сумматор и индикатор.A known electromagnetic structuroscope containing a series-connected generator, an eddy current suppressor, a multichannel amplitude-phase harmonic analyzer, an adder and an indicator.
Недостаток известного структуроскопа заключаетс в низкой надежности контрол объектов с необработанной поверхностью, так как результаты контрол существенно завис т не только от.физико-химических свойств объекта, но и от шероховатости поверхности.A disadvantage of the known structuroscope is the low reliability of monitoring objects with an untreated surface, since the results of the monitoring depend not only on the physical and chemical properties of the object, but also on the surface roughness.
Наиболее близким к предлагаемому по технической сущности вл етс электромагнитный структуроскоп, содержащий последовательно соединенные генератор , вихретоковый преобразователь, селективный усилитель третьей гармоники генератора и фазовый детектор,The closest to the proposed technical essence is an electromagnetic structuroscope containing a series-connected generator, eddy current transducer, selective third-harmonic amplifier of the generator and a phase detector,
соединенный опорным входом с выходом вихретокового преобразовател через блок формировани опорного напр жени , и регистратор 2.connected to the reference input with the output of the eddy current transducer through the reference voltage generating unit, and the recorder 2.
Однако и этот структуроскоп не обладает необходимой надежностью контрол , что также св зано с существенным вли нием шероховатости поверхности на результаты контрол .However, this structuroscope does not have the necessary reliability of control, which is also associated with a significant effect of surface roughness on the control results.
Цель изобретени - повышение надежности контрол .The purpose of the invention is to increase the reliability of the control.
