基于Patran二次开发的飞机尾翼有限元建模方法

Finite element modeling method of aircraft empennage based on Patran secondary development

分析几种有限元建模的方法和平台的优缺点,用Patran的PCL通过增设特定的命令和窗体等开发飞机尾翼建模模块,并集成材料特性模块,形成一套由总体布局的几何信息直接生成,可进行应力分析的有限元建模系统.

The characteristic of three methods of building finite element models are compared. The PCL in Patran is used to build models quickly. In the process, a few special windows are used to form the system of building models. The material property module is integrated in the system. So the system is developed to improve the work efficiency.
