摘　　要：苹果碰撞后，两个苹果的总损伤体积与吸收能量线性相关；总损伤体积与接触面积之间呈５／２次方的线性关系；恢复系数随碰撞能量以非线性的方式变化，该系数并可作为显著损伤的临界值。This paper studies the bruises of free impacts between pairs of apples.The results showed that the total bruise volume of two apples was linearly correlatedwith the energy absorbed. The total bruises volume and the contact area had a five-sec-ond power linear relationship. The coefficient of restiution varied in a non-linearmannerwith impact energy.It could be used as a threshhold for serious bruisesin appltappleimpact.
