Finite element analysis about solar sail

The article is a structural analysis about a new space probe-solar sail. The model was designed and generated by our group, and it has been produced and deployed successfully on ground. The loads on outer space was introduced and expressed with equation. As a special state, the largest load around earth was used to analyze the model by the finite element method. We got some results about strain and stress, after setting some initial parameters. Compared with the results in the literature, the results presented here were credible. So our model, method and parameters can be used in solar sail analysis.
