水下爆炸气泡能载荷对单层板架塑性变形的影响研究

Effect of Bubble Energy Load by Underwater Explosion on Plastic Deformation of Single-Layer Stiffened Plate

    摘要
  • 摘要: 针对气泡能载荷对单层板架在水下非接触爆炸载荷作用下塑性变形的影响问题,运用能量法原理,计算了考虑气泡能载荷影响的单层板架的塑性变形,计算结果与试验结果一致。在此基础上,分析了径距比与由气泡能引起单层板架变形占总变形的比例之间的关系。结果表明：在计算工况下,气泡能载荷对单层板架塑性变形的影响不可忽略,其所引起的单层板架变形占总变形25%左右。

     

    Abstract: Effect of bubble energy load on plastic deformation of single-layer stiffened plate when subjected to non-contact explosive load was studied.The energy method principle was applied to calculate the plastic deformatio n taking into account the effect of bubble energy load.The results show a well agreement with the experimental results.Based on this,the relationship between the ratio of explosion distance to bubble radius and the rat io of deformation caused by bubble energy load accounting for the total deformations were analyzed.The results show that the plastic deformation by bubble energy load accounts for 1/4 total deformations of single-layer stiffened plate,which cannot be neglected in calculation practice.
