Analysis and Optimization of Corrugated Plate Under Explosion Load

对爆炸载荷下波纹夹芯板的防护性能进行了研究,分析了夹芯层材料厚度、夹芯层高度、外面板厚度及内面板厚度对防护性能的影响规律;采用优化拉丁超立方设计与径向基(RBF)神经网络方法,建立了波纹夹芯板的防护性能近似模型,在此基础上研究了动态响应对各影响因素的敏感度;采用MIGA与NLPQL相结合的组合优化设计方法,对波纹夹芯板进行了优化设计。结果表明:优化后,相同爆炸载荷下,波纹夹芯板内面板监测点的最大位移降低了79.7%,最大加速度降低了72.5%,波纹夹芯板的防护性能得到明显提升。

The research on the barrier property of corrugated plate under explosion load is carried.The sandwich thickness,sandwich height,outside plate thickness and inside plate thickness were selected as influence factors.On this basis,the influence law of barrier property was studied.Based on the optimized latin hypercube design and RBF method,the approximated model of barrier property of corrugated plate was established and the sensitivity analysis was proceed.The combined optimization design method was adopted to conduct the barrier property optimization research.The results shows that:the maximum deformation of monitoring points is reduced by 79.7%and the maximum acceleration is reduced by 72.5%.We can draw the conclusion that the barrier property of corrugated plate has a significant raise.
