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。 Pear vibration tests were conducted to study the effect of vibration acceleration and vibration frequency on pear damage under the condition of stable vibration. The relationship between the number of vibration N and the damage energy of pears during vibration from vibration to loss of commerciality was analyzed. The effects of vibration acceleration, The relationship between the frequency of vibration N1 and N2 and the frequency ω1, ω2 of vibration when pear vibrates to loss of commerciality at different frequencies. The experimental results show that the greater the vibration acceleration, the more prone to injury pear; the same acceleration conditions, the smaller the vibration frequency, the more prone to injury pear.
