Stand for dynamic tests of technical products in the mode of amplitude-frequency modulation with hydrostatic vibratory drive

The article reviews the problems arising during the development of the stand for dynamic tests of technical products in the mode of amplitude-frequency modulation with hydrostatic vibratory drive. It is possible to control the change of the modulating function law and get various spectrograms of the oscillatory process and the oscillation mode with amplitude-frequency modulation, which allows to achieve the maximum effect of vibration tests in the stand.
