摘要
研究了以泡沫铝为基体,以聚氨酯为增强体组合而成的泡沫铝-聚氨酯复合结构,其综合性能优于原组成材料而满足各种不同的要求。利用Ansys软件建立了泡沫铝-聚氨酯缓冲包装装置模型,通过分别填充体积比例为4.31%,8.04%及12.15%的泡沫铝,用Ansys对缓冲包装装置进行了应力分析,得到了装置各部分的变形情况,分析了装置的冲击吸振性能;仿真结果表明:在加速度达到7 800g时,该装置缓冲性能优于单体。
The authors studied foamed aluminium polyurethane composite structure, which is a combination structure with foamed aluminium as basal body and polyurethane as reinforcing body. Its overall properties were better than the original compositions, so as to meet various different requirements. Ansys software was utilized for establishing cushion packaging device model of foamed aluminium-polyurethane, through filling of foamed aluminium whose volume proportion is respectively 4.31%, 8.04% and 12. 15% , and stress analysis was performed to the cushion packaging device by Ansys. and the deformation of each part of device was obtained, and the impact damping performance of the device was analysed. Simulation results show that thee shock cushioning performance of the device is superior to the monomer when the acceleration reaches 7 800 g.
