| 目的 探索整体包装件的仿真分析方法。 方法 首先对整体包装进行定频振动试验分析， 得到产品响应加速度曲线， 然后建立整体包装件的有限元模型， 运用有限元软件 Ansys Workbench 中的瞬态动力学模块（Transient Structural）对其进行了振动仿真分析， 得到了包装件的响应加速度、总体位移、等效应力、各向应力等结果。 结果 由仿真所得响应加速度及试验结果的对比验证了仿真的可靠性， 并对缓冲衬垫的动态缓冲特性进行了分析， 发现缓冲衬垫内侧承受了较大应力， 在振动过程中起主要缓冲作用 ， 而上部护角衬垫外侧边角稳定性稍弱。 结论 可采取增加厚度的优化措施来提高缓冲保护功能，为非线性材料整体包装件的有限元仿真分析提供了一种可行的创新方法。 |

| Objective To explore the simulation analysis method of overall package. Methods Vibration test under particular frequency was conducted and the responsive acceleration curve of the product was obtained. Ansys Workbench （Transient Structural） was applied for the vibration simulation analysis of the whole package, which provided the results of responsive acceleration, total deformation, equivalent stress, normal stress. Results The accuracy of the simulation was verified by comparing the responsive acceleration of the simulation and the test. Dynamic cushioning property was analyzed. The results indicated that the inside of the cushioning package supported larger stress and played a main cushioning role, and the stability of upper cushioning package edges was low. Conclusion Optimization measures such as increasing the thickness could improve the protection function of the cushioning pad. The study provided a feasible and creative method for nonlinear overall package fem simulative analysis. |
