| 摘 要： | 基于Patran/Nastran有限元分析软件的后台文件,采用PCL（Patran Comm and Language）对Patran/Nastran软件进行了二次开发,建立了用于导弹吊挂强度分析的参数化、自动化方法。提出的方法实现了吊挂结构强度分析过程中的参数化建模-自定义网格划分-材料边界选择-强度分析-结果查看等整个过程的自动化。方法的应用可以方便开展吊挂结构随意改变尺寸、材料参数、边界等的强度分析。并且方法对于任意结构在有限元分析中尺寸、网格、材料、边界等参数化建模及有限元分析均可适用。

| Abstract: | In this paper,using the PCL(Patran Command Language) on Patran/Nastran software for the re-development,the structural strength parametrical and automated analysis method on the missile hanging structural is established on the basis of background documents of Patran/Nastran finite element analysis software.The proposed method can realize the process of the parametric modeling-mesh-material selection-analysis-results view for the whole strength analysis automatically of hanging structural.The application of this method is convenient for strength analysis of hanging structural with random dimensions,material properties,load boundary etc.This method is also suitable for parameters(size,mesh,material,load boundary) modeling in finite element analysis of arbitrary structure. |
