摘要
[目的]为了分析不同的舷侧防护结构抗导弹战斗部动能穿甲的防护性能,[方法]设计单层均质钢装甲结构、双层格栅防护结构等舷侧防护结构,采用数值仿真方法对比不同的舷侧防护结构阻拦中型亚音速半穿甲反舰导弹战斗部的效果。[结果]研究结果表明:采用形式简单的单层均质钢装甲作为舷侧防护结构时,需采用力学性能优良且厚度50 mm以上的某高强度钢,并且在实船应用中还应考虑薄、厚板间施工以及异种钢电位差腐蚀等问题;而采用双层格栅舷侧防护结构则可以避免上述问题。对于双层格栅防护结构,在重量一定的条件下,通过将重量资源分配给内层板以增加内层板厚度,可以显著提高双层格栅结构的整体防护能力。[结论]研究成果可为水面舰船抗导弹动能穿甲舷侧防护结构设计提供参考。
[Objectives]This paper aims to analyze the protective performance of different broadsideprotection structures subjected to semi-armor-piercing missile warheads. [Methods]Single-layerhomogeneous steel armor structures and double-grid protection structures are designed,and the protectiveperformance of different broadside protection structures in blocking medium subsonic semi-armor-piercingmissile warheads is compared via numerical simulation. [Results]The results show that it is easy todesign single-layer homogenous steel armor for use as broadside protection structure,but high strengthsteel with excellent mechanical properties should be used and the thickness should be more than 50 mm. Inaddition,consideration should be given to the construction of thin plates and thick plates,as well as theelectrochemical corrosion of different types of steel. The above problems can be avoided by using adouble-layer structure as the broadside protection structure. For double-grid protection structures,theweight resources should be allocated to the inner plate by increasing its thickness,thereby improving theoverall protective ability of the double-grid protection structure.[Conclusions]The results of this studycan provide useful references for the design of broadside protection structures capable of withstandingsemi-armor-piercing missile warheads.
