Abstract

To analyse the influence factors of impact peak force (IPF) and damage depth (DD) on potatoes, the orthogonal test and single factor test were carried out on two potato varieties. The results showed that the IPF of Xiabodi was smaller and DD was greater than those of Gaoyuanhong. Potato mass had the greatest effect on IPF, and that of drop height on DD. The equations between IPF, DD and potato mass, drop height were obtained. Both IPF and DD impacting with steel were the largest, and the smallest with steel- rubber. With the increase of impact times, IPF decreased first and then increased, and DD increased gradually.

为了分析各因素对马铃薯碰撞峰值力和损伤深度的影响，分别对两个品种马铃薯进行了正交试验和单因素试验。结果表明：夏波蒂的碰撞峰值力小于高原红，损伤深度大于高原红。马铃薯质量对碰撞峰值力影响最大，下落高度对损伤深度影响最大。试验得出了碰撞峰值力和损伤深度与马铃薯质量和下落高度之间的方程式关系。马铃薯与不锈钢碰撞的峰值力和损伤深度最大，与不锈钢-橡胶最小。随着碰撞次数的增加，碰撞峰值力先减小后增大，损伤深度逐渐变大。
