Abstract

Recently, the use of nanosatellites in the space industry has been receiving increased attention. For the robust construction of a nanosatellite, the structure of the nanosatellite needs to be able to protect avionics and payloads from launch and space environments. In this study, we performed the structural design and analysis to build and implement a robust structure for the Korea Microgravity Science Laboratory nanosatellite. To this end, quasi-static and random vibration analyses were numerically conducted by applying a load of 18.75 G (specified by the GSFC-STD-7000 regulations) to the designed structure. The predicted natural frequency of the designed structure for the nanosatellite was greater than the resonance frequency of the launch vehicle. Additionally, the robustness of the structure was confirmed by the numerical results obtained from the quasi-static and random vibration analyses.

Keywords:
