FIELD: testing equipment. SUBSTANCE: gear including circuit of automatic keeping of acceleration amplitude is supplemented with circuit of automatic phase tuning of frequency. Stabilization of level of load on articles is carried out simultaneously with tuning of excitation frequency to resonance frequency of resonator which changes in process of testing. EFFECT: enhanced reliability and precision of testing. 2 dwg
