| 摘要: |
| 缓冲材料的物理特性与厚度对苹果的碰撞损伤有显著的影响。当缓冲材料的弹性模量较小时，缓冲性能较好，随着缓冲材料弹性模量的增大，碰撞时间与接触面积逐渐减小，最大加速度与损伤体积相应增大。在一定范围内，随着缓冲材料厚度的增加，碰撞时间与接触面积线性增加，最大加速度与损伤体积相应减小。 |

| Bruise Reducing by Cushion Materials in Apple Impact |
|
|
| Abstract: |
| The physical properties and thickness of cushion materials have remarkable influence on impact bruise.The cushion properties keep higher when the elasticity
modulus of cushion materials is lower. The impact time and contact area are reduced
with the modulus of elasticity increment. In a definite scope, the impact time and contact
area are linearly increased while the maximum acceleration and bruise volume reduced
with the increment of thickness of cushion materials. |
