| 摘要: |
| 利用振动试验台,进行了苹果运输振动损伤的模拟试验。结果表明:当振动频率为2Hz,加速度>1. 0×9. 8 m/s2时,包装箱内与各层包装箱的加速度均大于振动台面的加速度,且由底层向顶层递增;包装箱内损伤体积中层>底层>顶层;这两种工况的损伤体积均随加速度的增加而线性增加;加缓冲材料可使损伤体积减少50%。 |

| Simulation of Vibration Damage in Apple Transportation |
|
|
| Abstract: |
| Simulated tests of vibration damage in apple transportation were performed by using vibration testing machines.The results indicated that the acceleration in
packing box and between box layers increased not only from the bottom to top but also
greater than that of the vibration table,when the frequency was 2Hz and the acceleration above 1. 0×9. 8m/s2.The middle layer damage volume in packing box was more serious than that of the bottom and the bottom still more than that of the top.The damage
volume showed an linearity increment with the acceleration increase.With cushion materials the damage volume could be reduced by 50%. |
