Abstract

Distribution of supporting point has a significant impact on dynamic characteristics for the folding solar panel. In order to study the effect of supporting point distribution on the fundamental frequencies of folding solar panel, a typical single folding solar panel with four point support is taken as the investigation object. Based on the conservation of energy principle and Rayleigh-Ritz theory, the vibration equation and the frequency equation are established for analyzing the free vibration problem of folding solar panel with points support. The vibration characteristics of the folding solar panel with four points symmetrical support is gained, and Aiming at the maximum fundamental frequency to the support points for optimization distribution is also discussed. The examples show the theoretical calculation results have good consistency with the results of the finite element analysis. The research results could provide a theoretical basis for the preliminary design of supporting point distribution for the single folding solar panel.
