A Mirror Method for Measuring Directional Patterns in the Auxiliary (Azimuthal) Plane of Angle Transducers
Source abstract
Abstract
A new mirror method is proposed for measuring directional patterns of angle piezoelectric transducers in an auxiliary (azimuthal) plane. Measurements of directional patterns in the auxiliary plane were carried out for transducers with angles of probe ranging from 34° to $$70^\circ $$ using the mirror method on a steel sample with plane-parallel surfaces. It has been established that for transducers with wedge angles close to the first critical one (probe angle $$34^\circ $$ ), the beam angle of the directional pattern in the auxiliary plane widens; this can be explained by a refracted longitudinal (head) wave participating in pattern formation. It is shown that directional patterns can be effectively measured in the auxiliary plane of piezoelectric transducers for azimuthal angles ranging within $$ \pm 15^\circ $$ from the acoustic axis.
