| Abstract: | By comparing two schemes of solar array structures, including the layout and the connections, the influence of the structure damping on the acceleration response for the solar sensor is analyzed based on the analysis of structure response sensitivity. Meanwhile, according to the vibration test results for the two schemes, it is shown that the roof response is increased by 27.1% with reduced number of fixed connections in the sideboard and with increased quantity of the solar cells, better than the test conditions. Also, the longitudinal and transverse fundamental frequencies are decreased to some extent as compared with the results of the initial scheme. Therefore, as viewed from the structure characteristics, the initial design scheme is more reasonable. |
