摘　　要：防护水舱作为抵御反舰武器爆炸破片和冲击波效应的有效手段之一,在舰船防护结构中经常被采用。爆炸冲击波是一种瞬态的作用,水舱在这种瞬态冲击载荷作用下的响应涉及内、外板以及舱内水的相互作用,其响应机理十分复杂。迄今为止人们还没有对其进行比较完整和严格的理论分析。文章通过适当的假设,对防护水舱内外舱壁在接近爆炸载荷作用下的响应机理进行了理论分析,推导出了水舱内、外板的响应计算公式,并做了算例研究。文中的研究对防护水舱这种特殊结构抵御爆炸冲击波的机理有了进一步的理论解释,并对其设计提出了可供参考的依据和原则。As one of the most efficient instrument to resist against the anti-warship weapon＇s fragments and explosion shock,the protective tank is widely used in war ship protective structure.The explosion shock is a sort of transient load.The research on the response of the protective tank under such transient load consists of the outer and inner plate of tank and the interactive effect of structure and the water in it. Because of the complexity of the mechanisms there has not been investigated in theory so far.Therefore,a theory research on the response of the warship protective tank; under near-by explosion is provided in this paper.The velocity response equations about the outer and inner plate of the protective tank are developed. Finally,a typical example is calculated.A logical explanation of the mechanisms of protective tank can be concluded by this study.Some principles are promoted for the use of protective tank design.
