目的 从缓冲材料应力-应变曲线生成对应的缓冲曲线，并设计一系列软件界面。方法 基于图片的像素值，提取已发表文献的缓冲材料应力-应变数据。结果 以EPS泡沫材料为例，得到了其缓冲系数-最大应力曲线和最大加速度-静应力曲线，并利用Matlab/GUI得到了用户界面。结论 该方法为包装设计提供了有效途径。

The work aims to obtain the corresponding cushioning curves based on the stress-strain curves of the cushioning materials and design a series of software interfaces. According to the pixel values of the image, the stress-strain data of the cushioning materials in the literatures that have been published were extracted. Taking EPS foam material as an example, its cushion coefficient-maximum stress curve and maximum acceleration-static stress curve were obtained. Moreover, Matlab/GUI was used to obtain the user interface. This method provides efficient ways for package design.
