Electrodynamic vibration test stands is a vibration testing or calibration installation, on the active basis of which objects for vibration tests and vibration measuring devices are installed, on which calibration / calibration and various studies are carried out. In turn, test shakers are divided into special-purpose shakers and universal shakers. The frequency and range of oscillations of the working base of the universal electrodynamic shaker should be smoothly regulated in a strict range by means of vibration test coordination.
The test shaker is designed for a long service life, has a strong margin of resistance to diametral vibrations and a rigid axial ratio. The vibration tables of the stands are provided with an air load compensation system, which guarantees the preservation of a stable state of the working platform even with a large weight of the tested object.
