ANSYS的二次开发技术在稳定型悬索桥建模中的应用

Application of Second Development of ANSYS to Stable Type Suspension Bridge Modeling

基于大型通用有限元分析软件ANSYS环境,利用其二次开发功能,实现了对稳定型悬索桥的参数化建模。此开发使用的是APDL+UIDL模式,可以根据输入的桥梁长度、加劲梁节段长度、主缆及倒缆线形等数据生成相对应的有限元模型。它具有适用范围广、重用性好的特点。

Based on the finite element method, the modeling of stable type suspension bridge based on second development of ANSYS was realized. This development used the model of APDL＋UIDL. The finite element method model is generated from the input of the bridge length, the strengthen beam section length, the main cable, and the downward cable line, etc. Therefore, it can be widely used and reused.
