ABSTRACT To analyze the influencing factors of impact force on potatoes, a mathematical model between the impact peak force , the potato mass and the drop height was established as . A single-factor impact test was carried out, and the models for , and were presented as and . Taking the combination form of and as the test factor, the of two potato varieties, namely, Xiabodi and Gaoyuanhong, were tested under the impact materials of steel, steel-soft plastic, steel-rubber and steel-leather. The relationships between and were all under the four types of impact materials by the regression analysis of the test results. The range of was from 980.9 to 1395.7. The effect of potato variety on was analyzed. The results showed that under the same conditions, the of Xiabodi was 8.03 N smaller than that of Gaoyuanhong on average, which indicated that Xiabodi had a better tolerance to impact force. The effect of impact material on was analyzed. The results showed that with steel, steel-leather, steel-rubber and steel-soft plastic decreased in turn, and the average difference between the maximum and minimum value of was 16.6 N.

马铃薯冲击峰值力测量

摘要 为分析马铃薯冲击力的影响因素，建立冲击峰值力、马铃薯质量与跌落高度之间的数学模型。进行了单因素冲击试验， 和 的模型表示为 和 。以 和 的组合形式为试验因素，在钢、钢-软塑料、钢-橡胶、钢-皮冲击材料下对夏波地和高远红两个马铃薯品种进行了试验。通过对试验结果的回归分析，两者之间的关系均在四种冲击材料下。的范围是从 980.9 到 1395.7。分析了马铃薯品种对马铃薯的影响。结果表明，在相同条件下，夏波地的平均比高远红小8.03 N，说明夏波地对冲击力有较好的耐受性。分析了冲击材料的影响。结果表明，随着钢、钢-皮革、钢-橡胶和钢-软塑料依次下降，最大值与最小值的平均差值为16.6 N。
