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.
