    摘要:

    针对目前樱桃番茄储运过程中主要包装形式以及造成破损的情况,选择典型运输包装件,进行了正弦扫频、堆码强度、堆码扫频振动传递性能、垂直冲击和跌落试验。通过对单件包装件的扫频振动试验,测出单件的固有频率为26.61Hz;通过堆码强度试验,测出了包装件的最大堆码层数为9层。通过9层堆码扫频振动传递性能试验确定了底层、中间层和顶层包装件的固有频率分别为36.61、10.76和6.44Hz,得到了各层包装件振动加速度、振动传递率随时间的变化曲线,并探讨了固有频率和振动传递率峰值与堆码高度之间的关系。在此基础上,通过垂直冲击试验,测出了产品的脆值为89.58;通过跌落试验,测出了包装件最大允许跌落高度为580mm。

    Abstract:

    In view of the main packing form and damage of cherry tomatoes in storage and transportation process in nowadays, the main reasons for the damage of cherry tomatoes package were studied. By choosing a kind of typical cherry tomato packages in the circulation market, five real tests, which included sinusoidal vibration test at variable frequency, vertical impact and dropping tests as well as stacking strength test and vibration transmissibility of multipackages stacking test, were carried out according to the national test standards. Through sinusoidal vibration test at variable frequency on the single layer package and stacking strength test, the resonance frequency and maximal stacking layers were determined respectively: the natural frequency of a single package was 26.61Hz and the maximal stacking layer was 9. Then, the natural frequencies of every layer package were determined by 9 stacking layers vibration transmissibility experiment at variable frequency, and they were 36.61, 10.76 and 6.44Hz for the bottom, middle and top layers respectively. Curves of acceleration and vibration transmissibility of every layer package vs time were obtained. The relationships of its natural frequency and peak value of vibration transmissibility vs stack height were discussed. On the basis of the above, the fragility of each package was 89.58 by carrying out the vertical impact test. Also, the allowable maximal dropping height is 580mm according to the dropping test. Finally, the protection capability of the packages on cherry tomatoes was evaluated and some suggestions were also given.
