摘要
基于正交试验法分析了翼板厚度、腹板厚度、横筋间距及翼板高度等结构参数对复合材料上层建筑板架抗核爆性能的影响,得到了各结构参数对板架中心最大变形、面比吸能、中心加速度3个抗核爆考察指标的影响程度,给出了考虑单个指标时的板架较优结构参数组合及综合3个指标时的优化结构参数组合,并对比了优化结构参数组合下,复合材料板架与典型钢制板架的抗核爆性能。结果表明,复合材料板架较钢制板架的中心最大变形减小了26.0%,面比吸能增加了107.7%,质量降低了64.6%,中心加速度峰值增加了234.5%,在牺牲加速度的前提下,复合材料板架减小了中心最大变形,增加了面比吸能,且实现了减重。本文研究结果可为复合材料上层建筑抗核爆性能的结构优化设计提供参考。
Based on orthogonal test method, the effects of structural parameters such as the flange plate thickness, the web thickness, the transverse stiffeners spacing, and the wing plate height of the composite grillage on the anti-nuclear explosion performance are analyzed. The influences of the structural parameters on three anti-nuclear explosion indexes, including the maximum center deformation, the surface area specific energy absorption, and the central acceleration, are obtained, and the optimal combination of structural parameter of the grillage considering a single index is given. The optimum combination of structural parameters of the grillage is synthesized with three indexes, and the anti-nuclear explosion performances of composite plates and typical steel plate are compared under the optimum combination of structural parameters. The results show that the maximum deformation of the composite plate is reduced by 26.0% compared with the steel plate, the surface area specific energy absorption is increased by 107.7%, the weight is reduced by 64.6%, and the peak value of the central acceleration is increased by 234.5%. Under the premise of sacrificing the acceleration index, the composite plate reduces the maximum deformation of the center, increases the surface area specific energy absorption and achieves weight reduction. It provides a reference for the structural optimization design of composite superstructure with nuclear blast resistant.
