ULTRASOUND MODE OF DEFINITION OF THE ANGLE OF THE INPUT OF LONGITUDINAL WAVES INTO A TWO-PLY ARTICLES

摘要

FIELD: (57) the invention is assigned for definition of the angle of the input of longitudinal waves in a two-ply articles. ^ SUBSTANCE: the essence is in that they define the angle of the input of the longitudinal wave alpha1 and the speed of the surface wave Cr1 in a standard model and the speed of the surface wave Cr2 on a controlled object. After that they calculate a correction coefficient k in relation to Cr1/Cr2 and define the real angle of the input of the longitudinal wave in the controlled object according to the formula: alphareal=arcsin(alpha1 k), where alphareal - the real angle of the input of the longitudinal wave in the controlled object; alpha1 -the angle of the input of the longitudinal wave on the standard model; k - a correction coefficient. ^ EFFECT: increases accuracy of definition of the angle of the input of longitudinal waves in a two-ply articles. ^ 2 dwg
