FIELD: testing equipment.
SUBSTANCE: invention relates to test equipment and can be used for investigation of vibration isolation systems. Method consists in installation of two identical analyzed objects on different systems of vibration isolation thereof and carrying out of measurements of their amplitude-frequency characteristics. Then obtained characteristics are compared and conclusions on vibration isolation efficiency of each of analyzed systems is made. At the same time to determine fundamental frequencies of each of analyzed systems of vibration isolation simulation of impact pulse loads is performed on each of systems and waveforms of free oscillations are recorded, decoding of which shows intrinsic frequencies of system and logarithmic decrement of oscillation damping of each of investigated two-mass vibration isolation system.
EFFECT: technical result is expansion of technological capabilities of testing objects having several flexible links with aircraft structural parts.
