Numerical Simulation on Shock Initiation of Performed Fragment to Warhead

JIANG Zeng-rong1,2,LI Xiang-rong3,LI Shi-cai1,WANG Hai-fu2(1.The Second Research Department,Equipment Research Institute of PLA's Second Artillery,Beijing 100085,China;2.State Key Laboratory of Explosion Science and Technology,BIT,Beijing 100081,China;3.Department of Arms Engineering,Academy of Armored Forces Engineering,Beijing 100072,China)  
The mechanism of high-speed performed fragment shocking and initiating cruise missile warhead was analyzed.The high-speed fragment shocking and initiating warhead was simulated by using ignition and growth model and AUTODYN.The effect of material,diameter,shape of fragment and the charge and case of detonated warhead on shock and initiation was mainly studied.The result shows that the high density and irregular fragment with the same mass is easier to shock and initiate warhead.Using heavy metal and irregular fragment,increasing the diameter and velocity of fragment,the power of shock initiation can be improved.
