FEM Analysis of inversely Casting Stainless Steel Strip in the Level Rolling by ANSYS Program
-
摘要: 利用ANSYS有限元分析軟件對反向凝固不銹鋼復合帶的平整軋制過程進行了變形物理場分析,得出了復合帶平整軋制時內部各點的塑性應變和應力分布:軋件內存在不均勻變形,母帶的應變大于凝固層,凝固層應變從表面向內部逐漸增大;在軋制變形區內,凝固層的應力大于母帶;軋件的殘余應力約為19 MPa.軋制力的解析結果與實測的軋制力基本相符.Abstract: Deforming physical field of inversely casting austenitic stainless steel strip during level rolling process was analyzed by ANSYS program. Plastic strain and stress of all the nodes were gained, which shows:There exists uneven deformation in the strip. Strain of the mother sheet is larger than that of the growth layer. Strain of the growth layer becomes larger from surface to inside. In the deformational zone, the stress of the growth layer is larger than that of the mother sheet. The residual stress in the strip is about 19 MPa. The rolling force estimated with ANSYS program is corresponded to those measured.
