Beschreibung
Zusammenfassung:	FIELD: physics. ^ SUBSTANCE: device contains platform for test object fixed by rod with sealed piston attached to crank gear link, flywheel, crank radius changer, synchronously rotating left and right lead screws radially mounted within flywheel, nuts fixed on the crank and adjoining the screws herewith one-way advancing, rack-type differential with two driving and two driven wheels. Two driven wheels of rack-type differential are rigidly connected to the screws and established on two shafts. The first shaft is provided inside of the second shaft. While rotating both shafts are decelerated with brakes. The drive of vibration-testing machine presents driving motor and all-purpose speed regulator enabling platform vibration frequency control and gear reversal of the flywheel. Hermetic enclosure is controlled with control unit through valve assembly and connected to high pressure source. The flywheel is supplied with brake mechanism. ^ EFFECT: extended testing resources of vibration-testing machine, possibility to design alternating dynamic seismic loadings. ^ 1 dwg
