FIELD: machine building.
SUBSTANCE: invention relates to vibration testing equipment, namely, to devices (benches) for tests for vibration effects of aircraft rockets in laboratory bench conditions. Proposed device comprises two unidirectional rotary vibration exciter connected with appliance with standard suspension assemblies to carrier aircraft and portals for signage. Vibration exciters are installed on hollow power frames, consisting of 2 parts: upper and lower, and inside upper parts of frames there are grip assemblies, to which the article is attached through suspension assemblies.
EFFECT: technical result consists in creation of universal dynamic bench for accurate simulation of real loads during vibration tests, obtaining complete and reliable information on loading of the structure of the article during operation, as well as simplifying the design, reducing its weight and power consumed during operation.
