摘要
目前的塑性加工三维有限元分析软件存在着不能直接进行优化设计的关键问题 ,严重制约了这些软件的应用效果 .为解决此问题 ,比较分析了有限元法和上限元法的优、缺点 ,它们的缺点必须用含有更具体的专业基础理论的单元分析法才能克服 ,因而提出塑性加工的模型元分析法 .初步说明模型元分析法的基本原理、解题思路 ,以及模型元分析法与有限元法、上限元法在同一环境中的互补关系 ,证明模型元分析法的适用性 .指出模型元分析法是实现塑性加工分析软件智能化与优化设计功能的可行方法 .
There are key problems in the actual 3D FEM software that can't optimize design directly,which restricted the applied effect in plastic forming. MEM(model element method) is first proposed to solve the problems because it makes use of the element method that contains more concrete specialized basic theories to overcome FEM and UBM's shortcomings. Its main principles,the idea of solving process and the complementarity among MEM,FEM and UBM are briefly described in the article to prove the applicability. In conclusion,MEM is a feasible method to intelligentize analysis software and optimize design in plastic forming.
