多舱防护结构水下接触爆炸吸能研究

摘要

The breakage of warship structure subjected to contact underwater explosion will be very serious. The large-scale warship is inclined to be defended by sacrificing space which can absorb much more explosive load.Utilizing the result of a series of underwater contact explosion experiments,and calculation of load energy and energy absorded by structure, this paper analyses the ratio between load energy and the energy absorbed,and the energy distribution influence aroused by the quality of explosive and structure parameters. The research is helpful for improving anti-damage capability of shipboard defense structure.%接触爆炸条件下,舰船结构破损非常严重,大型水面舰艇的多舱防护结构以空间换防护,可将接触爆炸载荷层层吸收,从而保护防护结构内部的各个舱室.文章根据一系列水下接触爆炸试验,结合水下接触爆炸载荷下作用载荷能量和结构破损吸能计算,分析了爆炸载荷能量与结构总吸能的比例关系,以及药量、结构参数对总吸能分配的影响,对提高多舱防护结构抗爆能力具有一定的参考价值.
