Construction of a new damage estimation theory by applying damage boundary curve-Packaging optimization for fresh produce-

为了估计冲击对新鲜农产品的损害，本文提出了一个模型，利用S-N曲线来证明每次冲击时冲击加速度（Acc）与损害程度(D)之间的关系。在该模型中，假设在各种冲击条件下，每次冲击的D随速度变化（Vc）和Acc的组合而变化。因此，我们研究了Vc和Acc组合对草莓在几种冲击条件下的损伤发生的影响。我们的结果表明，每一次休克D随Vc和Acc的组合而变化。

For the estimation of damage to fresh produce subjected to shock, a model has been proposed to demonstrate the relationship between shock acceleration(Acc) and the damage degree(D) for each instance of shock by applying the S-N curve. In this model, it is assumed that D per one time of shock varies with the combination of velocity change(Vc) and Acc under various shock conditions. Thus, we investigated the effect of the combination of Vc and Acc on the damage occurrence in strawberry subjected to several shock conditions. Our results suggested that D per one time of shock varied with the combination of Vc and Acc.
