STAND FOR DETERMINING eigenfrequency and generalized masses of the test object, excludes the effect of moving mass vibrator on the defining characteristics

摘要

The invention relates to the field of test equipment, in particular to a test frequency of mechanical structures, provides the experimental determination of the quantities and distributions of the masses of natural frequencies of the test structures, free from the influence of the test equipment and can be used in mechanical, wind power, etc. The proposed technical solution solves the problem of experimental determination of the dynamic characteristics (natural frequencies and generalized mass) of the test object itself. To achieve the above technical result the stand to determine the frequency and generalized mass of natural oscillations, having a discharge farm or the power rack, a soft suspension system or for docking the test object device with a power bar, a set of special electrodynamic shakers, a set of transient elastic members for connecting the test object with movable parts vibrators EFD, specialized control and measuring and computing complex, doukomplektovyvaetsya set dobavoch s cargo to be mounted on the moving parts of the vibrator or an additional set of EDV with other mobile masses.
