| 目的 研究某新型导弹包装箱跌落工况下的冲击动力学响应，校核箱体结构是否满足设计要求。方法 采用有限元仿真技术，研究包装箱结构跌落冲击动力学行为。建立箱体结构三维仿真模型，分析水平跌落和棱边跌落等2种工况，得到箱体的应力分布以及加速度响应，进一步对仿真分析结果的可靠性进行试验验证。结果 2种跌落工况下，箱体所受最大应力均小于材料的屈服极限。经跌落试验测试，箱体结构完好，无损伤和变形，试验结果与仿真结果吻合。结论 有限元分析结果合理可靠，包装箱结构性能满足设计要求。 |

| The work aims to study the impact dynamic responses of a new missile packaging box under drop condition and check whether the box structure meets the design requirements. The finite element simulation technique was used to investigate the dynamic behavior of packaging box with drop impact. The three-dimensional simulation models of the box were established. Level drop and edge drop were analyzed, respectively. The stress distribution and acceleration response of the box were obtained, and the reliability of the simulation analysis results was verified by experiment. The maximum stress on the box was less than the yield limit of the material under the two drop conditions. After drop experiment, it could be found that the box had no damage and deformation, which agreed well with the simulation results. The finite element analysis results are reasonable and reliable, and the structural property of the packaging box satisfies the design requirements. |
