摘要
基于某舰船的船底板架，设计出了四边形蜂窝夹层板结构单元，比较分析了船底板架、等效平板、夹层板在典型工况（炸药量500kg，爆距15m）水下爆炸冲击波载荷作用下的损伤变形、结构位移、吸能及运动响应，同时对比分析不同冲击因子下3种结构的防护性能。分析表明，夹层板在水下冲击波作用下的最大变形是船底板架的2／3～1／3处，一定程度上改善了冲击环境，具有优越的防护性能。
Based on traditional ship bottom stiffened plate, square honeycomb sandwich plane was designed in this paper. Then the deformation,displacement, distortional energy and motion response of three different type plate namely traditional stiffened plate, equivalent plate and square honeycomb sandwich plane were investigated with explosive weight 500 kg and explosion distance 15 m. The anti-shock capacity was then further studied with different shock factors. Results show that the deformation of square honeycomb sandwich plane is 2/3 -1/3 to the stiffened plate, and its shock environment is also been improved. Square honeycomb sandwich plane owns a superior anti-shock capacity than other two plates.
