The work aims to study the vibration and shock characteristics of the refrigerator during the distribution. The model for cushioning packaging of the refrigerator was established by Pro/E and the model was properly simplified. Then, the vibration and shock characteristics of the refrigerator's cushioning packaging were simulated, analyzed and calculated with the finite element analysis software Ansys. The natural frequencies and vibration modes of the refrigerator's cushioning packaging were obtained, and the dynamic responses to the vibration and shock during highway transportation were obtained. The proposed method that simulates the vibration and shock characteristics of product packaging system not only shortens the design period, but also provides the basis for the packaging design of the electronic products.
