FIELD: machine building.
SUBSTANCE: method means installation of two similar tested objects on different vibration insulation systems, and measurement of their amplitude-frequency characteristics. Then the obtained characteristics are compared, and conclusions are made on the efficiency of vibration insulation of each tested system. At that to determine natural frequencies of each tested system of vibration insulation the impact pulse loads on each system are simulated, and oscillograms of free oscillations are recorded.
EFFECT: extension of process possibilities of testing of the objects having several elastic constraints with hull structures of the aircraft.
