针对冷轧钢卷包装中多层材料的接触变形问题,对钢卷包装系统的抗凹性进行了分析与研究；建立了考虑层间作用的钢卷包装系统的力学模型，计算和分析了钢卷的变形和应力,应用HYPERMESH与ANSYS/LS-DYNA对钢卷抗凹性模型进行了有限元仿真；最后进行了抗凹性模型的冲击试验，验证了有限元仿真计算结果，可为钢卷包装工艺设计提供理论依据。

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.
