| 中文摘要: |
| 提出了晶体学模型来研究多层薄膜滚压的表面粗糙度。研究了单层滚压模型，提出滚压的三维模型和二维模型（平面应变），讨论了晶粒大小和应力状态的影响。把单个单层滚压和多层滚压模型、三维模型和平面应变模型进行了比较，发现对于所涉及的二维和三维模型来说，单层滚压和多层滚压模型并无明显的差别。因此在这些情况下，可以用单个单层滚压模型来代替多层滚压模型从而节省CPU时间。 |
| 英文摘要: |
| A crystallographic model has been presented for the surface roughness modelling of thin sheet rolling.Single sheet rolling model and pack rolling model are studied by three and two(plane strain) dimensional models.The influences of the grain size and stress states have been analysed.Comparisons have been made between the single sheet model and double sheet model,and between the three dimensional simulation and plane strain simulation.For the 3D and 2D models studied here,there is not obvious difference between the single sheet model and pack rolling model.So in some cases,the single sheet model can replace the pack rolling model to save CPU time.The 2D model gives a higher prediction of surface roughness than 3D model. |
