BENCH FOR STUDY OF VISCOELASTIC PROPERTIES OF METALS AND ALLOYS USING ACOUSTIC SONDE METHOD

摘要

FIELD: test equipment.;SUBSTANCE: present invention relates to the field of metallurgy and mechanical engineering. The task to be solved by the declared invention is the determination of viscoelastic properties of metals using the acoustic sonde method. The stand for study of viscoelastic properties of metals consists of the variable signal setting generator, an induction mechanical oscillator the elastic element of which is designed as a thin metal beam with a shock sonde fixed on it, and also a sample for study to which the piezoelectric sound pickup is connected. The signals from the generator and the sound pickup are sent to the two-channel computer oscillograph.;EFFECT: technical result is the possibility of non-destructive diagnostics of viscoelastic properties of metals and alloys by means of measurement of amplitude of the acoustic signals occurring at impact of the sonde onto the solid body surface.;5 cl, 3 dwg
