摘　　要：采用CATIA R18软件建立弹翼参数化的有限元模型。通过有限元软件MSC.Pastran对模型进行多种合理化简化,主要对于螺栓连接方式进行几种不同方式的简化连接,并各自应用有限元接触隐式非线性分析方法使用MSC.Nastran求解器对弹翼考虑接触情况下的模态和各连接件间的接触应力应变进行有限元计算分析。对比各种模型的弹翼应力应变是否符合结构强度要求。CATIA R18 software based on the wing of the parametric finite element model is used,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 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.
