TEST RIG FOR VIBROACOUSTIC TESTS OF SAMPLES AND MODELS

摘要

FIELD: machine building.;SUBSTANCE: device contains base on which by means of at least three vibrator isolators a partition is secured, if is single weight oscillating system. The eccentric vibrator is used as generator of harmonic oscillations, it is installed on the partition, on the partition the rack to test natural frequencies of the resilient elements of spring and disk vibrator isolators with different length, geometrical parameters, and weight, they are secured at ends of these tested elements. At that oscillations of the weight secured on each resilient element are registered by the movement indicator, according to its readings the resonant frequency corresponding to the parameters of each resilient element is determined. On the base and partition the vibration acceleration sensors are secured, their signals enter the amplifier, then oscillograph, magnetograph and PC for processing of the received information, at that for the test rig setting frequency meter and phase indicator are used.;EFFECT: extension of process possibilities of testing of the objects having several elastic constraints with hull parts.;4 cl, 7 dwg
