基于UG的膨胀套管螺纹接头参数化建模

Parametric Modeling of Expandable Casing Joint Based on UG

膨胀套管螺纹接头优化设计分析时需要反复修改接头参数,高效快速建立接头三维模型,本文提出了两种利用UG软件进行膨胀套管螺纹接头参数化建模的方法.在UG中完成接头模型样板后,第一种方法通过Visual Studio开发平台编写程序得到一个可改变结构参数的可执行程序,实现膨胀套管接头二次开发建模;另一种方法是基于PTS模块完成对话框设计,通过重用库实现参数化建模.文章给出了膨胀套管接头三维参数化建模实例.通过本文的参数化建模方法能有效减少膨胀套管螺纹接头数值分析时的重复建模时间,提高工作效率.

In the optimization design and analysis of expandable casing joints,it is necessary to modify the joint parameters repeatedly and establish the 3D model of the joint efficiently and quickly.This paper presents two parametric modeling methods of expandable casing joints with Unigraphics(UG).After the joint model template is completed in UG,one of the two methods uses the development platform Visual Studio to write an executable program with modifiable structure parameters and thereby achieve the secondary development and modeling of the expandable casing joint.In the other method,a dialog box is designed on the basis of the PTS module and parametric modeling is performed through the reuse library.An example of 3D parametric modeling of expansion casing joints is also provided in this paper.The proposed parametric modeling method can effectively reduce the repeated modeling time in the numerical analysis of expandable casing joints and improve work efficiency.
