目的 研究冰箱在运输过程中的振动和冲击特性。方法 利用Pro/E建立冰箱缓冲包装模型，并对模型进行适当简化，然后利用有限元分析软件Ansys对冰箱缓冲包装的振动和冲击特性进行模拟分析计算。结果 求出了冰箱缓冲包装的固有频率与固有振型，以及在公路运输过程中受到振动和冲击下的动态响应。结论 所提出的模拟产品包装系统的振动和冲击特性的方法，不仅缩短了产品的设计周期，而且为电子产品的包装设计提供了依据。

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.
