摘要
采用显示动力有限元软件LS_DYNA模拟双层壳结构在两种不同形状的撞头撞击下的响应,通过分析比较发现,双层壳结构抵抗球形撞头撞击的能力更强。
The response of the double-shell under the impaction of the bows with two kinds of shape is simulated by ls-dyna in this article. And from the analysis of the results,we find that the shape of the bow has great influence on the crashworthiness of the dubble-shell.
