Abstract

The structure of a satellite, during its operational life, must be tolerated all applied mechanical loads which the most important of them is vibration loads during the launch. To ensure the verification of design of the satellite structure, finite element analysis and vibration tests should be performed on the structure of satellite according to the ECSS standard. In this paper, while simultaneously examining the optimal design process for a satellite structure with an increase in the strength to mass ratio, the required finite element analyzes along with the mechanical tests of the structure of a telecommunication satellite, including random vibrations, sinusoidal vibrations, shock and quasi-static, are fully presented. The results showed that by employing the cross section design for the satellite structure, the natural frequency of the satellite in the longitudinal direction have increased appreciably, which increases the strength of the satellite in the longitudinal direction. Also, the results of the conducted tests proved that the designed structure meets the frequency requirements of the launcher while tolerate the mechanical loads during launch. The results of the tests were in good agreement with the finite element analysis, including the modal analysis, random and sine vibrations and indicate the verification of the design of the satellite structure
