The vibration transfer characteristics of the product packaging system are investigated through numerical simulations and experiments， and the vibration response of the product packaging system is investigated under the excitation of the band limited white noise spectrum and ASTM truck highway spectrum. The state-space method and MATLAB/Simulink simulation tools are used to carry out random vibration simulation analysis of the product packaging system to investigate the effect of cushion liner ma‐ terial parameters on the frequency response transfer function of the path and the dynamic response of the product. The results are as follows： among the four vibration transfer paths of the product， the frequency response transfer function and the vibration response of the mass block are larger in the path with large mass distribution and large stiffness； the damping parameters inside the product on the path have no effect on the frequency response transfer function and the acceleration response of the mass block on each path； the acceleration response on the key component is between the response of each part of the product； a larger cushion liner damping helps to reduce the resonance peak of the acceleration response power spectrum （PSD） on the key component， and larger cushion stiffness increases both the PSD resonance frequency and the resonance peak of the key component’s response. The external excita‐ tion spectral patterns， the vibration transfer characteristics of the system and the excitation spectral energy near the resonance fre‐ quency all have effects on the damping effect of the cushion liner. The random response law of the product packaging system under the simulation analysis is consistent with experimental study， and the results provide a theoretical basis for product packaging de‐ sign.
