摘要
为了缩减U型槽钢系列产品设计周期，可借助参数化设计实现槽钢模型分析的调整。利用有限元软件ANSYS提供的APDL语言，采用有限元方法对U型钢辊弯成形过程进行仿真，将参数化设计的思想融入有限元结构分析，实现了有限元建模和分析参数化，给出了这一方法与基本步骤。结果表明，这种方法极大地减少了有限元分析的工作量，提高了工作效率。研究表明，提出的参数化有限元法对辊弯U型槽钢实用、可行，为辊弯成形数值模拟探索出了一种高效、快捷、实用的新方法。
For the series of U--channel section, which has similar structure, it is easy to adjust the geometric model of U --channel section by using parametric design method, the efficiency is improved and the time for product design will be short- ened greatly. By using the ANSYS Parametric Design Language （APDL）, the FEA process including creating FEA model and analysis steps is discussed with the finite element method. A practical parametric FEA model is established and using this method does stress analyse. The results show that this method is very efficient in FEA of structure optimisations. The re- search shows that parametric finite element method proposed for process parameter optimization of roll forming is accurate and reliable. And a new efficient method is explored on numerical simulation of roll forming.
