Studying a Signal due to the Tangential Component of Stray Fluxes from a Surface Flaw Detected with a Vibrating Induction Transducer

Аннотация

Analytical dependences of the amplitude spectrum of the output signal of a vibrating induction transducer on its position with respect to a flaw and on vibration-displacement parameters have been derived. The locality of inspection and its selective sensitivity toward flaws have been evaluated. The results of theoretical research have been confirmed experimentally.
