Abstract
Изобретение относитс к неразрушающему контролю качества структуры отливок из высокопрочного чугуна с шаровидным графитом. Цель изобретени - повышение информативности контрол . Преобразователь содержит размещенные в корпусе 1 демпфер 2, пьезоэлемент 3, протектор 4, посто нный магнит в виде пары кольцевых секторов с противоположной пол рностью в плоскост х и центральным углом α, установленных контактно к демпферу 2, и резиновое опорное кольцо 8, ограничивающее пространство, заполненное ферромагнитной жидкостью 9. Преобразователь снабжен электромагнитом с П-образным магнитопроводом 10, который смонтирован в корпусе 1 так, что его полюса охватывают посто нный магнит, демпфер 2 и пьезоэлемент 3, причем продольные плоскости симметрии посто нного магнита и П-образного магнитопровода 10 перпендикул рны. 2 ил.The invention relates to non-destructive quality control of the structure of castings of high-strength nodular cast iron. The purpose of the invention is to increase the information content of the control. The converter contains a damper 2, a piezoelectric element 3, a protector 4, a permanent magnet in the form of a pair of ring sectors with opposite polarity in planes and a central angle α installed in contact with the damper 2, and a rubber support ring 8, which limits the space, filled with ferromagnetic fluid 9. The converter is equipped with an electromagnet with a U-shaped magnetic core 10, which is mounted in the housing 1 so that its poles encompass a permanent magnet, a damper 2 and a piezoelectric element 3, STI symmetry of the permanent magnet and the U-shaped yoke 10 are perpendicular. 2 Il.
