FIELD: testing equipment.
SUBSTANCE: invention relates to testing equipment. On a base by at least three vibration isolators a bulkhead is secured representing a single-mass oscillating system with weight and rigidity m2 and c2, respectively. Harmonic oscillations generator used is an eccentric vibrator arranged on the bulkhead. Natural frequencies testing stand for resilient elements of spring and plate vibration isolators is mounted on bulkhead. Vibration isolators have different length, geometrical parameters, different value of loads fixed at the ends of the tested elements. Oscillations of a load fixed on each resilient element are registered by a displacement indicator, according to readings of which resonant frequency is determined, corresponding to each resilient element parameters. On the base and the bulkhead vibration acceleration sensors are fixed, signals from which are transmitted to an amplifier, an oscilloscope, a magnetograph and a computer to process the received information, herewith to adjust the bench operation a frequency meter and a phase meter are used.
EFFECT: technical result of the invention is expansion of technological capabilities of testing objects having several resilient links with structural parts.
