基于Ansys二次开发的网架结构优化设计

Optimum design of grid structures basing on re-development of Ansys

通用有限元软件Ansys具有强大的结构分析能力,但由于没有内嵌中国的设计规范,因此其分析结果一般不能直接作为设计结果来使用.本文将设计规范和常用的杆件类型通过APDL二次开发技术内嵌入Ansys中,并在其中进行优化分析计算,实现了在Ansys中一次性完成网架结构的分析与优化设计工作.

Widely used software Ansys has a powerful structural analysis ability. But it does not inclu Chinese design standard of structures, so the result of analysis can not be directly applied for design. T structural standard and the usual types of member are integrated into Ansys with re-development meth by APDL, and optimization of the grid structure can be carried out with directly used outcome.
