利用ANSYS实现斜拉桥非线性分析

Application of ANSYS in nonlinear analysis in cable-stayed bridges

ANSYS软件是融结构、热、流体、电磁场、声场和耦合场分析于一体的大型通用有限元分析软件。利用ANSYS的二次开发技术,如用户界面设计语言(UIDL)、参数化设计语言(APDL)以及用户可编程特性(UPFs),可以实现对ANSYS的用户化定制,使ANSYS在特定的应用范围内发挥更大效率。本文着重介绍利用ANSYS进行斜拉桥非线性分析的实现过程,并在最后给出了应用实例。

The ANSYS program is a general finite element analysis software.It can be used in structure,thermodynamics,hydrodynamics,electromagnetics and so on.ANSYS provides three developing techniques to users,including User Interface Design Language(UIDL),ANSYS Parameter Design Language(APDL) and User Programmable Feature(UPFs).Based on the APDL developing techniques,a fundamental procedure for nonlinear analysis in cable-stayed bridges is presented.At the end,in order to verify the method,a example is given.
