Abstract: 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.
