| Abstract: |
| For solving the multi-layer contact deformation problem of cold rolled steel coil, dent resistance of steel coil packaging system was analyzed and studied. Mechanical model of steel coil packaging system considering interlayer effect was established and the strain and stress of the steel coil was calculated and analyzed. FEM simulation of dent resistance of the steel coil was carried out by using HYPERMESH and ANSYS/LS-DYNA. An impact test of the dent resistance model was carried out to verify the FEM simulation. The purpose was to provide theory basis for steel coil packaging process design. |
