Laboratory Test of Vibration of Micro/Nano Satellite for Environment Test Standardization

This paper presents the basic research for establishing the qualification test (QT) level which the units have to pass to be sold as products for space usage. A laboratory test campaign has already begun for the study how the mechanical stresses distribute within the satellite body so as to define the unit QT level. In order to achieve that we carried out random vibration tests using a dummy satellite (50cmx50cmx50cm) and measured the distribution of acceleration inside the satellite. The research focuses on the provision of the physical basis of the test conditions to be defined in the new standard. We tried to identify the range of natural frequency and acceleration in the launching environment. The main parameters taken into consideration for analysis are the resonant frequencies and amplification of acceleration. The detailed test procedure, analysis method and primary results are herein reported.The 29th International Symposium on Space Technology and Science (29th ISTS), June 2-9, 2013, Nagoya, Aich
