船用泡沫铝夹层板在低温下的冲击动态响应研究
|
摘要
泡沫铝夹层板具有良好的动态能量吸收性能,在极地船舶抗冲击防护方面具有巨大的潜在应用前景。文章利用ABAQUS有限元软件,结合准静态拉伸压缩材料试验,建立了船用泡沫铝夹层板的低温动态冲击数值仿真模型,研究了其动态冲击响应与抗冲击性能,并采用Instran 9350落锤冲击试验机对数值仿真模型进行了试验验证。在此基础上,研究了低温和冲击能量对船用泡沫铝夹层板动态冲击响应的影响。结果表明,随着冲击能量的增加,常温和低温条件下船用夹层板的冲击力峰值、最大挠度和最终挠度遵从乘幂增长规律。与常温相比,低温下船用泡沫铝夹层板的面板变形较小,且随着冲击能量的增加,低温的影响更为显著,即船用泡沫铝夹层板在低温下具有更好的抗冲击性能。
Aluminum foam sandwich plate(AFSP) has excellent energy absorption capability, thus it has potential application in the protective structures for polar ship. In this paper, the nonlinear finite element software ABAQUS is used to analyze the dynamic behavior of aluminum foam sandwich plate for lightweight ship at low temperature and room temperature. The accuracy of numerical method was verified by the comparisons of results between the experiment and the numerical simulation. Besides, a series of simulations is carried out to investigate the dynamic responses of AFSP when suffered from impact loadings under different impact energies at low temperature and room temperature. The results indicate that the peak impact force,max deflection and permanent deflection increase as the impact energy increases, following power law. The deflections at low temperature are smaller than those at room temperature, meanwhile, the effect of low temperature on the dynamic responses of AFSP increases with the increase of impact energy. It can be concluded that the impact resistance of AFSP at low temperature is better than that at room temperature.
