目的 研究如何对平板电视的包装衬垫进行合理设计和安全检验。方法 根据缓冲包装五步设计法选取合适的缓冲衬垫。利用有限元软件ABAQUS建立仿真模型并进行单元网格划分，结合显式动力学原理和平板电视撞击地面时弹性势能与时间的关系，对衬垫进行缓冲应力分析和强度检验。结果 通过仿真分析可得，平板电视落地的冲击应力远远小于衬垫能承受的最大应力。结论 在平板电视的配送过程中，以聚苯乙烯泡沫为材料的缓冲衬垫能对产品起到很好的保护作用。

The work aims to study how to reasonably design and safely check the package pad of the flat-panel TV. The suitable cushion pad was selected according to the five-step design method for the cushioning package. The simulation model was established with the finite element software ABAQUS and the unit grid was divided. In combination with the explicit dynamics principle and the relationship between the elastic potential energy and the time when the flat-panel TV hit the ground, the cushioning stress analysis and strength test of the pad were carried out. Based on the simulation analysis, the impact stress of the flat-panel TV hitting the ground was far less than the maximum stress to be borne by the pad. In the distribution process of the flat-panel TV, the cushion pad made of polystyrene foam can protect the product effectively.
