建立了双层堆码包装系统动力学模型，对双层堆码包装系统经过路面减速带时的运动情况进行了分析初步探讨了车速、减速带高度和缓冲材料刚度对运动的影响，并提出了降低冲击力对包装件损伤程度的措施。

The kinetic model for double-stack packaging system was established , and the motion of double-stack packaging system when it passed deceleration strip on road surface was anaiysed, the influence of vehicie speed, height of deceleration strip and buffer material rigidity on motion was preliminarily discussed. Measures for reducing the damage extent of package by impulse force is proposed.
