Vibration and Impact Performance Tests on Cherry Tomato Transport Packages
The reasons for damage to packaged cherry tomatoes in storage and transportation were investigated.By choosing a typical cherry tomato package, four tests were performed. These tests included: stackingstrength test, sinusoidal vibration transmissibility of multi-packages stacking test, vertical impact tests anddrop tests. The tests were carried out according to national test standards. It is determined by the stackingstrength test that the maximum number of allowable stacking layers is 9. The natural frequencies of layeredpackages were determined by using a 9 stacking layer vibration transmissibility experiment with a variablefrequency. The natural frequencies were 36.61 HZ, 10.76 HZ and 6.44 HZ for the bottom, middle and toplayers, respectively. Curves of acceleration and vibration transmissibility of every layered package versustime were obtained. The relationships of its natural frequency and peak value of vibration transmissibilityversus stack height were studied. On the basis of the above findings, the fragility of cherry tomatoes for eachpackage is 89.58 by carrying out the vertical impact test. Also, the allowable maximal dropping height is580mm according to the drop test. Finally, the protection capability of the packages on cherry tomatoes wasevaluated.
