Research on Rapid Modeling Methods for K-Joints Based on Finite Element

管节点是现代工程结构设计与强度分析中的重点。分析ANSYS参数设计语言的优势与局限,确定利用VB.net开发自动建模程序实现参数化建模总体设计方案。以K型管节点为研究对象,对单元类型的选取、网格划分的原则及方法等方面展开研究,通过VB.net一键生成K型管节点有限元模型命令流,实现K型管节点有限元快速建模,此研究方法可推广至其他形式管节点。

Pipe joints are the key points in modern engineering structural design and strength analysis.This paper analyzes the advantages and limitations of the ANSYS parametric design language,and decides to utilize VB.net for developing automatic modeling program to achieve the overall design of parametric modeling.Taking the K-joints as the research object,the selection of element types,the principles and methods of mesh division are studied.Through VB.net,a command stream for generating finite element models of K-joints is created,enabling rapid finite element modeling of these joints.Additionally,the research method can be extended to other types of pipe joints.
