Description
Устройство работает следующим образом .The device works as follows.
Наконечник 1 в виде полуконуса задавливают на требуемую глубину, грузом 5 удар ют по упору 3, и импульс через штангу 2 передаетс на наконечник 1, который возбу одает тюперечные волны типа SV или SH в зависимости от ориентации плоскости (X или У). Послеэтого наконечник 1 при помощи , штанги 2 разворачивают на вновь производ т удар.The tip 1 in the form of a half-cone is pressed down to the desired depth, a load 5 hits the stop 3, and the impulse is transmitted through the rod 2 to the tip 1, which excites tupereverse SV or SH waves depending on the orientation of the plane (X or Y). After that the tip 1 with the aid of, the rods 2 are turned on again to strike.
На осциллограммах получают записи колебаний упругих волн. Поскольку при перемене знака воздействи происходит инверси фаз вступлени поперечных; волн типа SV или SH, то это обеспечивает их надежное выделение.On oscillograms receive records of oscillations of elastic waves. Since, when changing the sign of the action, the inversion of the transverse entry phase occurs; waves like SV or SH, this ensures their reliable selection.
