针对马铃薯这类不易观察跌落损伤的果蔬产品,提出了一种测定其临界损伤跌落高度的方法。首先对马铃薯进行准静态压缩,得到其产生损伤时的压缩变形量。同时,通过测量马铃薯在不同跌落高度下的跌落信号,分析得到反映不同跌落高度与跌落变形量之间关系的数学模型。对应压缩变形量在此数学模型中的值,即可得到马铃薯的临界损伤跌落高度,为38cm。
針對馬鈴藷這類不易觀察跌落損傷的果蔬產品,提齣瞭一種測定其臨界損傷跌落高度的方法。首先對馬鈴藷進行準靜態壓縮,得到其產生損傷時的壓縮變形量。同時,通過測量馬鈴藷在不同跌落高度下的跌落信號,分析得到反映不同跌落高度與跌落變形量之間關繫的數學模型。對應壓縮變形量在此數學模型中的值,即可得到馬鈴藷的臨界損傷跌落高度,為38cm。

Potato is a kind of vegetable whose damage cannot be easily observed. Regarding to this property, a method to determine the critical damage dropping height is proposed. At first, quasi-static compression is conducted to the potato, and then the compressive deformation is obtained. Meanwhile, with the experiment to obtain the potato's dropping signal, the mathematical model reflecting relation between dropping height and dropping deformation can be obtained. The critical damage dropping height is gained from the model with previous compressive deformation, that is 38 cm.
