摘　　要：针对目前海南圣女果在储运过程中的主要包装形式以及造成破损的情况,选择典型运输包装件,按照国家测试标准进行定频、扫频、堆码、垂直冲击和跌落实验,研究圣女果包装件损坏的主要原因。通过振动实验,测出了包装件的共振频率为53.1 Hz;通过堆码强度实验,测出了包装件的最大堆码层数为9层。通过垂直冲击实验,测出了圣女果的脆值为93.84;通过跌落实验,测出了包装件最大允许跌落高度为550 mm。最后评价包装件在储运过程中对圣女果的防护能力,并提出改进建议。The reasons for damage to packaged cherry tomatoes in storage and transportation produced in Hainan China are investigated.By choosing a typical cherry tomato package,five tests are performed.These tests include： sinusoidal vibration tests at constant and variable frequency,stacking strength test,vertical impact test and drop test.The tests are carried out according to national test standards.By sinusoidal vibration at variable frequency test,the resonant frequency of 53.1 Hz is obtained.It is determined by the stacking strength test that the maximum number of allowable stacking layers is 9.Based on vertical impact test,it is verified that the fragility of cherry tomatoes for each package is 93.84.Also,the allowable maximal dropping height is 550 mm according to the drop test.Finally,the protection capability of the packages on cherry tomatoes is evaluated and some good suggestions are also given.
