战斗损伤仿真中的等效靶与破片终点速度研究

Equivalent Target and Terminal Velocity of Fragments in Battle Damage Simulation

概述了目前普遍采用的战斗损伤仿真分析方法,论证了其等效靶公式存在的缺陷。通过理论分析采用能量等效的原则建立了新的等效靶公式,取代了原来由强度等效得出的等效靶公式。选择了适用于战斗损伤仿真的极限速度公式,并提出了剩余速度的求解方法。利用前人做过的物理试验进行了验证。结果表明:建立的等效靶公式和剩余速度求解方法显著地提高了计算精度,可以应用于战斗损伤仿真分析中。

The battle damage simulation method was presented, meanwhile the disadvantage of equivalent target expression was demonstrated. New equivalent target expression was derived by theoretical ana-lysis based on the principle of energy equivalence instead of strength equivalence. The limit velocity formula adapted for battle damage simulation was chosen, and the method of calculating the terminal velocity was proposed. Validation was made by means of the experimental data, which come from other persons＇ paper. It is concluded that the equivalent target expression and the method of calculating terminal velocity can efficiently increase the calculating precision and can be used in the battle damage simulation.
