FIELD: test equipment.
SUBSTANCE: invention relates to test equipment and can be used for testing resilient elements of vibration isolators. 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, and as a generator of harmonic oscillations, an eccentric vibrator arranged on the bulkhead is used. On bulkhead post is installed for testing of natural frequencies of resilient elements of spring and disc vibration isolators with different lengths, geometrical parameters, as well as different weights value, fixed at these tested elements ends. 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.
