研究了多次拉深成形有限元建模中的几何建模、网格划分、材料和边界条件处理等关键技术。本文所阐述的技术对于多次拉深这一比较复杂的板料成形工艺的数值模拟研究有较大的参考价值。
The key technologies of geometric modeling, meshing, material and boundary conditions processing in the multi-drawing forming finite element modeling are studied. The technique described in this paper is of great reference value for numerical simulation of the more complex sheet forming process with multiple drawing.
