Abstract. Results of a study of a simulator of a transport and launch container designed for conducting vibrationdynamic tests of CubeSat 6U standard nanosatellites are presented. The frequency analysis of the device is carried out in CAD SolidWorks in the range from 5 to 140 Hz. As a result, two resonant frequencies of 42.25; 75.42 Hz in the Z plane and one — 42.25 Hz, for the X and Y planes, are identified. Results of full-scale tests of the designed device for searching resonances by measuring amplitudes and frequencies are presented. It is found that the frequency shift did not exceed 5% over the entire range, and the greatest amplitude shift is 18% at the frequency of 40.2 Hz in the Y plane. The obtained values indicate that the designed device can be used as equipment for vibration-dynamic tests of satellites. The discrepancy between the values of resonance frequencies obtained during full-scale and model tests did not exceed 5%, which satisfies the standard requirements for the convergence of measures.
