舱室内战斗部爆炸产生的冲击波是舱室结构板架承受的主要载荷之一,舱室内爆冲击波在舱室内部将发生多次反射,并在舱室内部形成持续时间较长的准静态压力,在此过程中舱室板架承受多次冲击波反射载荷。本文以舱室典型加筋板为对象进行夹层板概念设计,选取面板厚度、背板厚度、夹芯壁厚及夹芯间距4个参数作为试验参数,以抗爆综合评价指标最小为目标,采用正交试验优化设计方法得到该加筋板结构在舱室内爆冲击波载荷作用下最优抗爆性能的夹层板结构,并对比最优夹层板与普通加筋板在舱室内爆载荷作用下的响应特征。研究表明,经过优化设计后的夹层板具有更好抵抗冲击波载荷的能力,正交试验设计能较好适用于夹层板结构优化设计。
Explosive loading is one of the loadings of warship structural under anti-ship missile, in case of explosive inside closed cabin, except for the first shock wave, warship structural suffer multiple reflection shock waves, and for enclosed environment of cabin, quasi-static pressure will continue for some time. Optimal design of square hole honeycomb sandwich panel by orthogonal test under explosion loading inside closed cabin was done, the panel thickness, backing plate thickness, sandwich thickness and sandwich space are acted test parameters, the minimum comprehensive performance evaluation index of anti-shock capability is the target, and to get the best anti-shock capability sandwich panel, the response of the best sandwich panel and stiffened plate under explosion loading inside closed cabin were compared, the research shows that the optimal sandwich panel has better anti-shock capability, and orthogonal test can be used for design of sandwich panel.
