摘　　要：根据线面相交原理,利用AutoCAD二次开发工具ObjectARX编写了梁式三分岔管体形设计与网格自动剖分程序,实现参数输入的界面化,可按要求对梁式三分岔管进行任意剖分,并将单元、材料等信息纳入设计,为有限元计算提供完整的前处理信息。给出了工程应用实例,进一步说明设计思想和使用方法。It is very difficult to design and obtain the finite element information of a trifurcation with reinforced girders because of its com plexity.Based on the principle of space line intersection of a plane,a program for the design and compartmentalization of trifurcation with reinforced girders was compiled using the ObjectARX.This program can automatically generate the f inite element information according the requirements of users and make the input of parameter simplified.The principle and method of using this program has bee n explained by an example in this paper.
