FIELD: testing equipment.SUBSTANCE: invention relates to testing equipment. Based on, at least, by means of, three vibration isolators bulkhead is secured, representing single-mass oscillating system with weight and rigidity mand c, respectively. Harmonic oscillations generator used is eccentric vibrator, arranged on bulkhead. On bulkhead post is installed for testing of natural frequencies of resilient elements of spring and disc vibration isolators with different lengths, geometrical parameters and different weights value, fixed at these tested elements ends. Oscillations of 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 base and bulkhead vibration acceleration sensors are fixed, signals from which are transmitted to amplifier, then oscilloscope, magnetograph and computer for received information processing. For test bench adjustment frequency meter and phase meter are employed.EFFECT: technical result of invention is expansion of technological capabilities of objects testing, having several resilient links with structural parts.5 cl, 7 dwg |
