Abstract
During launch, CubeSats experience an acceleration many times higher than the gravitational acceleration. Resultant dynamic responses could cause structural failures; therefore, it was necessary to perform structural numerical simulation, as well as experimental testing on the structure of MYSAT-1, the second CubeSat developed in the UAE, to predict its structural responses. Two different finite element models were developed for the structural analysis of MYSAT-1. Different quasi-static loading and vibration scenarios were simulated using the finite element analysis software Abaqus. Experimental testing was incorporated to validate and verify the aforementioned numerical results. Ultimately, the vibration experimental results validated the numerical analysis. Up to 1000 Hz, the high-detail finite element model successfully simulated the structure of MYSAT-1. Around 8 out of the 11 significant resonances were generated using the high-detail finite element modal analysis. The structure and configuration of MYSAT-1 were found to meet the launch requirements.
