Vibration analysis is a fundamental technique used to simulate the effects of a launch. This paper aims to use ANSYS modal and random vibration analysis to gauge its accuracies in simulating the structural integrity of the CubeSat. This investigation was motivated to contrast the frequency profile of a 3U CubeSat's vibration test result and simulated frequency profile. The obtained response Power Spectral Density (PSD) values are contrasted with the actual response - PSD values from a vibration test, and it was discovered that the response PSD data was generally shifted by order of magnitude with discernible peaks similar to the obtained testing data. Because of this, it can be implied that the variation in data arose from overt or inaccurate simplification of the Computer-Aided Design (CAD) models imported into ANSYS as well as coarse meshing techniques deployed. Even though this was the case, the results obtained from ANSYS could still be an acceptable method to gauge the rigidity of the CubeSat. The ongoing ambition of this investigation is to amend the current analysis model further and develop a robust vibration analysis framework that would allow CUAVA to anticipate the frequency profile of the prospective 6U CUAVA-2 CubeSat and appropriately modify the configuration if necessary to obtain a higher degree of confidence with the structural integrity of the satellite.
