FIELD: test equipment.
SUBSTANCE: invention relates to testing equipment. Stand contains a base on which, through at least three vibration isolators, a bulkhead is fixed, the bulkhead is a single-mass oscillatory system of mass and rigidity of m2 and c2, respectively. As a harmonic oscillations generator, an eccentric vibrator is used and placed on the bulkhead, on the bulkhead stand is installed for testing of natural frequencies of resilient elements of spring and disc vibration isolators with different lengths, geometric parameters, as well as of different mass values fixed at the ends of those tested elements. Herewith oscillations of the mass fixed on each resilient element is fixed by displacements 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, then an oscilloscope, a magnetograph and a computer to process the received information, for test bench adjustment frequency meter and phase meter are employed.
EFFECT: technical result is expansion of technological capabilities of testing objects having several flexible links with structural parts.
