目的 研究C楞瓦楞纸板的非线性包装系统在运输过程中的跌落特性， 建立非线性包装产品系统模型， 并得到系统动力学方程。方法 依据物品响应加速度小于许用值及材料用量最小化等2个原则， 进行缓冲包装优化设计并获得最优解。结果 所建立的缓冲模型， 可以直接用于缓冲包装设计。结论 克服了用最大加速度-静应力曲线来设计缓冲包装需要大量实验和较多数据的弊端， 为其他缓冲材料在缓冲包装设计中提供一般方法。

Objective The Drop characteristics of nonlinear packaging system were studied under the C-flute corrugated paperboard in the transport process, the dynamical model of the system was developed, and the numerical results of the dynamical equations were obtained. Methods According to item response acceleration is less than the allowable value and the amount of material to minimize the two principles, the optimization design of cushioning packaging and obtain the optimal solution. Results It is shown that this method is better than the maximum acceleration-static stress curves that need more test and data in designing cushioning packaging. Conclusion The results lead to some insights into design of cushioning packaging.
