| 目的 在不同微拱滚筋结构下对金属三片罐罐身进行抗压试验与模拟仿真，研究该结构下罐身的抗压能力。方法 首先，通过金属材料拉伸试验得到材料物理性能参数，并利用ANSYS Workbench/LS-DYNA 对1、1.5、2 mm等3种向外微拱滚筋结构的三片罐以及直身滚筋罐进行径向压缩仿真模拟，得到4种罐型在相同变形条件下的最大接触力。其次，通过对现有直身滚筋罐和罐身向外微拱滚筋1.5 mm的三片罐进行相同变形条件下的径向压缩试验，记录其最大压缩力。最后，对试验数据和有限元分析结果进行对比分析。结果 3种幅度的微拱滚筋结构对罐身抗压强度有不同程度的影响，其中微拱滚筋1.5 mm对罐身强度的影响最大，在保证罐身强度和内部容积的同时，可以采用0.23 mm厚度材料替代现有0.25 mm厚度材料。结论 金属三片罐罐身在向外微拱滚筋1.5 mm后，可以有效提升罐身的抗压强度，在罐身材料减薄、减量后可以节约11.42 %的材料使用量，在生产中有着重要意义。 |

| The work aims to explore the compressive test and simulation of metal three-piece can bodies under different micro-arch reinforcement structures, and study the compressive strength of the can bodies under such structures. Firstly, the physical property parameters of the material were obtained through tensile test of metal materials. ANSYS Workbench/LS-DYNA was used to simulate the radial compression of three kinds of three-piece cans with 1 mm, 1.5 mm and 2 mm outward micro-arch reinforcement structures as well as straight-body beaded cans, and the maximum contact force of the four types of cans was obtained under the same deformation conditions. Secondly, radial compression tests were conducted on the existing straight-body beaded cans and the three-piece cans with 1.5 mm micro-arch reinforcement structure under the same deformation conditions, and the maximum compression force was recorded. Finally, the test data and finite element analysis results were compared and analyzed. The compressive strength of the can bodies was affected by the three amplitudes of the micro-arch reinforcement structures, among which the 1.5 mm micro-arch reinforcement structure had the greatest effect on the strength of the can bodies. On the premise of ensuring the strength of the can bodies and the internal volume at the same time, 0.23 mm thick material could be used instead of the existing 0.25 mm thick material. The metal three-piece can body can effectively improve the compressive strength under the outward micro-arch reinforcement structure of 1.5 mm. After the can body material is thinned and reduced, 11.42% of the material can be saved, which is of great significance for production. |
