摘要
设计了一种几何模型,基于该模型用Dynaform对不同材料、不同板料厚度、不同拉深筋形状和尺寸与拉深筋的阻力之间的关系分别进行了研究,得出不同材料和不同板料厚度对拉深筋的阻力与材料的初始屈服应力之比影响不大,拉深筋形状和尺寸与拉深筋的阻力与材料的初始屈服应力之比有关等规律,并给出了其关系曲线。
One CAD model was built in this study. The relationships of different materials, different material gauges, different draw bead shapes and different draw bead sizes with the ratios of the draw bead resistance forces to the material initial yield stresses were studied respectively from the CAD model by using Dynaform. The study concluded that different materials and different material gauges slightly affected the ratios of the draw bead resistance forces to the material initial yield stresses. Al- so, it derived that the draw bead shapes and the draw bead sizes are related with the ratios of the draw bead resistance forces to the material initial yield stresses, and the relationship curves were presented.
