针对碳纤维复合材料无人艇，本文开展近场水下非接触爆炸载荷下复合材料小艇的动态响应研究。基于不同迎爆舱段下船体的动态响应数值计算，分析船体受到冲击后的应力和损伤特性。揭示了近场非接触水下爆炸对碳纤维复合材料无人艇的影响情况，为复合材料小艇抗爆性能优化的后续研究提供参考。
Aiming at the carbon fiber composite material unmanned boat, this paper carried out the research on the dynamic response of the composite material boat under the near-field underwater non-contact explosion load. Based on the numerical calculation of the dynamic response of the hull under different upset compartments, the stress and damage characteristics of the hull after the impact are analyzed. The impact of the near-field non-contact underwater explosion on the carbon fiber composite material unmanned boat is revealed, which provides a reference for the subsequent research on the optimization of the anti-blast performance of the composite material boat.
