Description
Известны ультразвуковые пластинчатые излучатели с криволинейной излучающей поверхностью цилиндрической и сферической формы.Known ultrasonic plate emitters with a curved radiating surface of cylindrical and spherical shape.
Описываемый излучатель отличаетс от известных тем, что в плоскости, перпендикул рной оси облучаемого круглого цилиндра, излучатель выполнен в виде части эвольвенты окружности , радиус которой меньше радиуса цилиндра.The described radiator differs from the known ones in that in the plane perpendicular to the axis of the irradiated circular cylinder, the radiator is made as part of an involute of a circle whose radius is smaller than the radius of the cylinder.
Такое выполнение обеспечивает эффективное возбуждение нормальных волн в стенке облучаемого круглого цилиндрического тела, например, при дефектоскопии труб.This embodiment provides an effective excitation of normal waves in the wall of the irradiated round cylindrical body, for example, during pipe inspection.
На чертеже показана схема работы описываемого излучател .The drawing shows the scheme of operation of the described radiator.
Излучатель 1, расположенный на эвольвенте 2 окружиостн 3, посылает ультразвуковые волпы на поверхность облучаемого круглого цилиндрического тела 4, причем в каждой точке облучаемого участка происходит синфазное сложение возмущений, создаваемых всеми точками новерхности излучател .The emitter 1, located on the involute 2 of the circumferential 3, sends ultrasound waves to the surface of the irradiated circular cylindrical body 4, and at each point of the irradiated area there is an in-phase addition of disturbances created by all points of the surface of the radiator.
