FIELD: test equipment.
SUBSTANCE: object to be tested is fixed onto table of resilient resonator, which is mounted onto platform of bed to be subject to impact impulse effect. One or several resilient resonators are mounted additionally between table of resonator and tested object depending on required range and level of frequencies excited in object; rigidity of resonators increases from platform to tested object. Natural frequencies of system formed by platform and resonators are tuned to frequencies which correspond to preliminary calculated minimums of Fourier amplitude spectrum of impact pulse reproduced by bed.
EFFECT: widened operational abilities.
