Description
Изобретение относитс к дефектоскопии цилиндрических изделий и может бы использовано дл определени параметро траектории сканировани и оптимизации параметров сканирующего устройства. Наиболее близким к предлагаемому по технической сущности вл етс спосо определени параметров траектории вращени сканирующего устройства, заключающийс в том, что на сканирующем устройстве устанавливают по крайней мере один преобразователь дефектоскопа вращают его вокруг цилиндрического контрольного образца с нанесенными на его поверхность искусственными дефек-. тами, а сигналы преобразовател регист рируют индикатором дефектоскопа ij. Недостатком известного способа вл етс невозможность определени амплитудных характеристик сканирующего уст ройства. Цель изобретени - повышение точнос ти определени параметров траектори . Поставленна цель достигаетс тем, что на поверхности контрольного образца вдоль его образующей нанос т одинаковые искусственные дефекты, размещают имитаторы/, неровности на поверхности контрольного образца, регистрируют изменение сигна,1ов от каждого дефекта , затем устанавливают контрольный образец с эксцентриситетом относительно оси вращени сканирующего устройства , снова регистрируют изменение сигналов преобразовател и по соотношению величины сигналов суд т о параметрах траектории вращени сканирующего устройства . На чертеже представлена схема устройства дл осуществлени предлагаемого способа. На опорах-подшипниках 1 устанавливают контрольный образец 2 с нанесенными на его поверхности вдоль образующей искусственными дефектами 3. Опоры-подшипники 1 закрепл ют, например, ковцент- рично или соосно с контролируемым ска-The invention relates to the flaw detection of cylindrical articles and can be used to determine the parameter of the scanning path and optimize the parameters of the scanning device. The closest to the proposed technical essence is the method of determining the parameters of the rotational trajectory of the scanning device, which means that at least one flaw detector transducer rotates it around a cylindrical test piece with artificial defects applied to its surface. The transducer signals are registered with the flaw detector indicator ij. The disadvantage of this method is the impossibility of determining the amplitude characteristics of the scanning device. The purpose of the invention is to improve the accuracy of determining the parameters of the trajectory. The goal is achieved by applying the same artificial defects on the surface of the test sample, placing simulators /, irregularities on the surface of the test sample, registering the signal change, 1 from each defect, then setting the test sample with eccentricity relative to the axis of rotation of the scanning device, The change in the signal of the converter is recorded again and the parameters of the trajectory of the scanning device are judged by the ratio of the magnitude of the signals. The drawing shows a diagram of an apparatus for carrying out the proposed method. A bearing sample 2 is installed on bearing bearings 1 with artificial defects 3 deposited on its surface along the generator.
