| 中文摘要: |
| 利用ANSYS有限元分析软件，通过对易拉罐不同跌落高度、不同碰撞地面的仿真分析，研究易拉罐在不同的跌落形式下的受力及变形。结果表明：随着跌落高度地增加，接触部位应力分布会扩大，并且应力也会相应地增加；面跌落相对于角跌落，应力会贯穿整个罐壁，并且向上出现不连续的传递，且逐渐减小。 |
| 英文摘要: |
| Simulation analysis of pop can with different drop height and floors was carried out using ANSYS finite element analysis software. The purpose was to study the force and deformation of pop can under different drop forms. The results showed that the contact stress distribution expands and the stress increases with drop height increase. For the flat drop, the stress of can runs through the whole can wall, discontinuously transmits upwards to the other sections of can and gradually attenuates, with respect of corner drop. |
