以波纹夹芯杂交夹层板（Hybrid Sandwich Plate with Corrugated-Cores, HSP）为研究对象，建立气-液-固三相数值模型，对结构在不同撞水速度下（1~10 m/s）动力响应特性进行数值计算分析。首先将其与相同质量的无填充轻质波纹夹芯夹层板（Light Weight Corrugated-Core Sandwich Plates, LWCCSP）在入水砰击下的非线性力学行为进行对比，分析探讨 2 种结构的能量吸收特点以及砰击压力和变形的分布规律，同时研究波纹夹芯杂交夹层板主要设计参数对其抗砰击性能的影响。分析结果表明，波纹夹芯杂交夹层板较同质量的无填充轻质波纹夹芯夹层板具有更好的抗砰击性能；在一定范围内，增加触水面板厚度及芯层厚度对提升波纹夹芯杂交夹层板的抗砰击性能有积极作用，且增加芯层厚度效果更为显著。
The dynamic characteristics of Hybrid Sandwich Plate with Corrugated-Cores (HSP) under different waterimpact velocities (1 m/s-10 m/s) considitions are studied in this paper. The computational models of multi-physics (air-water-solid) are built using finite element method (FEM). The energy absorptionslamming pressure and structure deformation of the HSP models are investigated, and compared to those of Light Weight Corrugated-Core Sandwich Plates (LWCCSP) models with the same mass. Furthermore, the influences of key parameters of HSP are studied. The results show that HSP has better anti-slamming performance compared to that of LWCCSP. Within a certain range, thickening the bottom plate and corrugated-core, especially the corrugated-core, has a positive role in improving the anti-slamming properties of HSP.
