| Abstract: | Using CATIA R18 software based on the wing of the parametric finite element model, through the finite element software MSC. Pastran to model the rationalization of simplified, mainly for bolt connection way different modes of simplified connection, and their application finite element contact implicit nonlinear analysis method using MSC. Nastran to play the solver wing consider contact case mode and the fittings of contact stress between strain finite element analysis and calculation of the wing of the contrast model of stress and strain is in accordance with the structural strength requirement. |
