摘　　要：通过梨的振动试验 ,研究了稳定振动条件下 ,振动加速度、振动频率对梨的损伤影响 ,分析了梨振动至失去商品性时的振动次数 N与损伤能量的关系 ,探讨了在相同振动加速度、不同频率下梨振动至失去商品性时的振动次数 N1 、N2 与振动圆频率ω1 、ω2 的关系。试验结果表明 ,振动加速度越大 ,梨越容易产生损伤 ;在相同加速度条件下 ,振动频率越小 ,梨越容易产生损伤。Through the experiment of pear vibration,the influences of vibrational acceleration and frequency on pear scathe under stationary vibration condition were studied. The relationship between the repetition number N of the vibrations which was the minimum number before the pear lost its marketability and the scathe energy was analyzed. Under the same vibration acceleration but different frequency,the relationship between the repetition numbers N 1?N 2 of vibrations and the corresponding vibration circle frequencies ω 1?ω 2 were also studied. The results showed that the pear would be more easily scathed when the acceleration was higher or the frequency was smaller under the same acceleration condition.
