Simulator of a Transport and Launch Container for Vibrodynamic Tests of CubeSat 6U Standard Nanosattelites

Abstract

Results of a study of a simulator of a transport and launch container designed for conducting vibration-dynamic 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.
