FIELD: testing equipment. ^ SUBSTANCE: invention is related to the field of testing equipment and may be used to create test benches and devices for investigation of dampers (anivibrators and dampers) of shaft oscillations. Device comprises base, which serves for installation of tested dampers, shaft, installed in two supports, one of which is arranged in the form of set of four frames arranged serially one into another and joined on opposite side by elastic elements in the form of plate springs equipped with vibration-survey converters, inserts and cartridge with the possibility of rotation in inserts fixed on central internal - first frame, and joined to the latter by means of elastic elements. Elastic elements on opposite sides of accordingly second and third, first and second frames are arranged in the form of two or more pairs, at the same time lengths of elastic elements between third and outer bearing frames are arranged at least as equal to width of the third frame. ^ EFFECT: provision of possibility to investigate oscillations in wide frequency range of forced oscillations without occurrence of resonances between own oscillations of elastic elements of frame support. ^ 2 dwg |
