Abstract
Based on demands of anti-terminal-sensitive projectile ,a preformed fragment war-heads is studied in this paper ,it is used to destroy deceleration and reducing rotation device of terminal-sensitive projectile, target detection sensor and the central processing unit. It puts forward programs of four different shapes of the fragments ,analyzes fragment velocity decay, gets its movement principles in space and calculate lethal area. It is also studied in different shapes of the fragments penetrating an aluminum target of finite thickness by Autodyn simulation in order to analyze ability of Fragment penetration in given distance and effects of penetration ability due to different shapes. Based on the results , programs are evaluated with Application of the Analsis Hierarchy Process(AHP).At last, the program is chosen to draw the structural diagram of projectile and calculate its structural parameters.
