| Abstract: | In order to obtain the fragment’s velocity characteristics of plane-symmetric warhead,the dynamic response of prismatic casing warhead under internal explosive loading is investigated based on energy analysis method.An Analytical method is proposed for calculating the initial velocity of fragment by adopting modified Hamilton principle.The research has shown that the theoretical resulted agreed with the experimental results.The calculated trend of fragment velocity distribution tendency is in concordance with the experimental measurement.The results provide important references for the improvement of operational effectiveness of High Speed Strike Weapon(HSSW). |
