| 目的 验证锂离子电池全纸化运输包装件的防护性能。方法 依据锂离子电池的产品特性、流通环境以及包装防护等多方面要求，选用合适的纸质包装材料得到全纸化的包装方案，选用仿真分析软件对包装件进行跌落模拟，得到其应力、应变等相关数据。结果 由跌落仿真分析可知，最大应力出现在外壳上盖凸台位置，其应力值为346.06 MPa，超过外壳最大许用应力值(325 MPa)，外壳发生破损。锂电池包装件跌落时，外壳等效应力值为1.211 MPa，仿真得到的应力值均未超过材料的许用应力，不会发生损坏。结论 该包装结构能够在运输过程中吸收大部分的冲击能量，能很好地保护内部产品不受损伤，具有良好的防护性能。 |

| The work aims to verify the protective performance of fully paper-based transport packaging for lithium-ion batteries. Based on the product characteristics, circulation environment, packaging protection and other requirements of lithium-ion batteries, a suitable paper packaging material was selected to obtain an all-paper packaging solution, and simulation analysis software was used to simulate the drop of the packaging parts and obtain their stress and strain data. As a result of the drop simulation, the maximum stress was 346.06 MPa at the top cover tab, which exceeded the maximum permissible stress value of 325 MPa and caused damage to the case. When the lithium battery packaging dropped, the equivalent stress value of the case was 1.211 MPa. The simulated stress values did not exceed the permissible stress of the material and no damage occurred. The conclusion shows that the packaging structure can absorb most of the impact energy during transport. It can protect the internal product well from damage and has good protective properties. |
