含能破片对运动靶的侵爆行为
Penetration-induced Initiation Behavior of Energetic Fragment for Moving Target
摘要
Abstract
To study the penetration‐induced initiation behavior of energetic fragment penetrating moving target ,the numerical simulation to penetrating moving target with different impact angles was conducted by AUTODYN‐3D software .The validity of the model was verified by a combination of experimental results and literature ones .The penetration‐induced initiation behavior of energetic fragment penetrating moving target was calculated .The results show that compared with a stationary target ,when energetic fragment penetrates moving target ,the fragment oc‐curs significant deviation ,and the perforation diameter gives large change .The residual velocity of fragment decrea‐ses with increasing the velocity of the target and the impact angle of the fragment ,and decline range is from 56 .25%to 77 .5% .The internal stress peaks of energetic materials change slightly ,almost as a straight line ,when fragment penetrating moving target compared with a stationary target ,the stress peak of energetic materials differs signifi‐cantly with different impact angles ,and the difference of the maximum peak can be up to 5 .2GPa .Under non zero impact angle ,the deflagration of energetic materials to be close to the target point does not easily take place .关键词
