耐压抗冲覆盖层在水下爆炸载荷作用下的冲击防护特性

Shock mitigation properties of compound claddings subjected to underwater explosion loads

  • 摘要:
      目的   为提高潜艇在水下爆炸载荷作用下的抗冲击性能,
      方法  基于潜艇冲击环境的特殊性,提出适用于其的耐压抗冲覆盖层结构,即塑性泡沫与橡胶复合的耐压抗冲覆盖层结构。运用数值仿真软件Abaqus/Explicit分析耐压抗冲覆盖层在静水压力和冲击载荷共同作用下的动态响应。
      结果  结果表明:当静水压力不超过覆盖层的屈服强度时,覆盖层的变形很小,可以有效降低冲击载荷; 当静水压力超过覆盖层的屈服强度时,覆盖层的变形很大,其抗冲击效果也有所下降。因此,耐压抗冲覆盖层的屈服强度应大于冲击环境的静水压力,同时应注意避免覆盖层发生密实化。
      结论   研究成果可为潜艇抗冲覆盖层的设计及研究提供参考。

     

    Abstract:
      Objectives  To improve the shock resistance ability of submarines,
      Methods  an anti-shock cladding for submarines which consists of a compound coating with rubber and plastic foam is proposed on the basis of the shock environment of submarines. The numerical model is established by Abaqus/Explicit to analyze the dynamic response of anti-shock cladding under the combined loads of hydrostatic pressure and underwater explosion loads.
      Results  The results indicate that the deformation of the cladding is negligible under hydrostatic pressure, and the shock load is largely mitigated when the yield stress of the cladding is higher than the hydrostatic pressure. Conversely, the deformation of the cladding is great under hydrostatic pressure and the shock mitigation effects of the coating are weakened when the yield stress of the cladding is lower than the hydrostatic pressure. As such, the yield stress of the cladding should be higher than the hydrostatic pressure, and densification should be avoided.
      Conclusions   The research findings in this paper can provide guidance for the design of anti-shock cladding for submarines.
