离散杆和EFP组合战斗部对飞机毁伤效应研究

为分析离散杆与EFP复合战斗部对典型战斗机毁伤效应,根据强度等效原则,采用动力学有限差分程序建立了数值模拟模型.采用流固耦合与接触算法,模拟了爆炸冲击波、离散杆条、EFP 3种毁伤元爆炸形成过程,以及典型弹靶交会条件下对飞机的联合毁伤效应.分析获得3种毁伤元对飞机各部分结构破坏、对油箱引燃概率的初步规律.研究结果对新型防空战斗部杀伤元素的设计及毁伤效应评估具有重要的参考价值.

Research on the Damage Effect of EFP Combined Warhead and Discrete Rod to Battleplane

In order to investigate the damage effect of discrete rod and EFP combined warhead on typicl battelplane,based on the strength equivalence principle,numerical simulation model were conducted with dynamic finite difference program.Numerical simulation of the formation process of three kinds of damage elements,which were blast wave,discrete rod and EFP,was achieved with fluid solid coupling and contact algorithm.And the joint damage effect on the aircraft under the condition of typical missile target encounter.Preliminary analysis of regulation of three kinds of damage element for aircraft parts of structural damage,the tank ignition probability was obtained.The research results had important reference value for the design of new air defense warhead and the damage effect evaluation.
