FIELD: testing.
SUBSTANCE: vibration test device relates to means for testing various instruments and devices on vibration test benches. Device for testing for effect of broadband random vibration has supports 1 with movable weights 2. Supports are rigidly fixed by one end on support plate 4, by other end are rigidly attached to box 3. Support plate 4 is fixed on the vibration test bench table. Moving the loads on the supports, the state is achieved, at which the root-mean-square value of accelerations along three coordinate axes on the tested device becomes the same. Then, tests for broadband random vibration with a given value of root-mean-square acceleration can be carried out.
EFFECT: elimination of unaccounted overload of equipment in two orthogonal directions of the main direction of action during tests on unidirectional broadband random vibration.
