| 摘 要： | 基于大型通用有限元分析软件ABAQUS计算平台,利用该软件提供的用户单元子程序UEL接口,以悬链线单元为基础,推导了迭代分析公式,向ABAQUS中添入悬链线单元的刚度矩阵及等效荷载列阵,扩充ABAQUS单元库,使悬链线索单元用于ABAQUS有限元分析,并采用Fortran语言开发了接口程序,研究结果表明,所研制的接口程序开发思路正确,计算精度满足要求。

| Abstract: | Based On the user-element subroutine interface provided by ABAQUS,a catenary cable element is established.The catenary cable element s stiffness matrix and equivalent load vector are induced and corresponding interface program is developed,in which Fortran language is adopted.ABAQUS element library are expanded.The feasibility and validity of the interface subroutine has also been proved. |
