基于PCL语言的梁截面自动生成

Automatic generation of beam section based on PCL

在船体结构有限元建模的过程中,定义梁单元是既重要又繁琐的步骤。一艘船上的骨材种类通常很多,在建模时需要定义很多的梁单元截面属性。文章利用通用有限元软件Patran中的PCL(Patran Command Language)语言,对Patran进行二次开发,使建模过程中的梁单元截面自动生成,节约了建模时间。

The beam property definition is a very important and elaborate part in the hull structural finite element modeling process. In general, there are plenty of beams or longitudinal types in one ship. Therefore, a great deal of beam section properties need to be defined. In this article, the Patran software is secondarily developed by using Patran Command Language（PCL）. The automatic generation of beam section property can be thus achieved to save the modeling time.
