中文摘要: |
采用有限元技术,应用MSC仿真软件分析铸造材料伸缩结构尾翼在弹道飞行过程中气动载荷矩阵作用下的接触应力问题。通过建立计算模型,施加边界条件及启动接触非线性求解器进行求解,得到尾翼三维结构下的位移和应力情况,该种MD Nastran隐式非线性求解器SOL600计算方法能够充分模拟实际三维结构的接触问题。 |
英文摘要: |
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. |
