| Abstract: | By using the finite element software MSC simulation analysis of the contact stress problem under pneumatic loading matrix was made to telescopic structure rear wing made by casting in ballistic during a flight. By establishing calculation model, exerting boundary conditions and starting contact nonlinear solver, the displacement and stress conditions of rear wing with three-dimensional structure were obtained. The MD Nastran implicit nonlinear solver SOL600 calculation method can fully simulate the contact problem of practical 3D structure. |
