目的 探讨由应力-应变曲线推导最大加速度-静应力曲线，进行发泡聚乙烯缓冲包装结构设计的方法。方法 利用发泡聚乙烯的应力-应变曲线推导得到最大加速度-静应力关系，结合算例验证方法的可行性。结果 得到了符合设计要求的缓冲材料的最小厚度值。结论 此方法丰富了包装动力学的基本理论，方便了缓冲包装结构设计。

The work aims to design the cushion packaging structure of foamed polyethylene by means of exploring the maximum acceleration-static stress curve induced by stress-strain curve. The maximum acceleration-static stress relationship was induced by stress-strain curve of foamed polyethylene and the feasibility of the method was validated in combination with example verification. The minimum thickness of cushion materials conforming to the design requirements was obtained. This method has enriched the basic theory on dynamics of packaging and facilitated the design of cushion packaging structure.
