含能破片爆炸驱动安定性研究
|
摘要
本文研究含能破片爆炸加速过程中安定性。在一维冲击波理论基础上研究爆炸驱动响应过程；研究不同隔爆材料对爆炸冲击波的衰减特性,以满足其抛射初速的情况下破片不破坏或者反应,进行了爆炸驱动过程的理论分析和数值模拟,验证了所设计的隔爆材料对冲击波的衰减性能。主要完成了以下几个方面的工作：
(1)分析了含能破片撞击目标靶的受力和作用时间,通过对含能破片冲击起爆机理分析,得出了含能破片的临界起爆能量判据,建立了含能破片冲击反应的临界起爆条件。
(2)针对含能破片战斗部作用的特点,建立了破片抛射速度和主装药、隔爆层、破片等参数的数学模型,通过研究爆炸冲击波在不同介质中的衰减规律,重点研究了采用三种典型隔爆材料的含能破片爆炸驱动作用过程,实现在满足一定爆炸驱动速度条件下,含能破片不发生破碎,填装的含能材料安定。
(3)数值模拟方面,针对所选的三种不同的隔爆材料,分别建立1／4有限元模型,对含能破片爆炸驱动作用过程进行数值模拟,验证了所设计隔爆材料在爆炸驱动过程中对冲击波的衰减性能。
(4)在理论分析和数值模拟的基础上,分析了隔爆层对冲击波的衰减性能和对含能破片的抛射初速的影响；进行了理论计算和数值模拟的比较,并对各影响因素进行了分析。结论可为含能破片战斗部结构设计提供依据。
Stability of energetic fragment during high velocity explosion driving is studied in this dissertation. Dynamic shock response under explosion driving based on one-dimensional shock wave theory is presented. Explosion interrupted material is used to attenuated the explosion load, and shock wave attenuation during it propagated in explosion interrupted material is analyzed theoretically.
Main contents in this paper as follows:
First, dynamic response during high velocity impact between the energetic fragment and the target are studied; Based on the theory of the impact initiation, the critical initiation energy of the energetic materiel in fragment is presented. At the same time, the critical initiation condition for energetic fragment is given out.
Second, based on the characteristics of fragment warhead, The mathematical model of the relationship between the initial velocity and the structural parameters of fragment projectile which include the high explosive charge, explosion-interrupted material, fragments and other components is presented. Based on the study of the attenuation law of the shock wave in different media, the explosion driving process of three typical materials is mainly analyzed. The results show that shock load in energetic fragment is significant decreased by using the interrupted material which ensure no broken and reaction in energetic fragments.
Third, three-dimensional computational studies are used to simulate the explosion driving process of energetic fragment by using finite element program of LS-DYNA.1/4 finite element is used to carried out the simulation. Typical shock wave propagation in interrupted material and energetic fragment is given out. The results agree well with the above analysis and the interrupted material has high value in attenuating the shock load in energetic fragment.
Fourth, Based on the theoretical analysis and numerical simulation, the influence of shock wave attenuation of interrupted material to initial velocity of energetic fragment is analyzed. A comparison between theoretical model and numerical simulation is carried out. The result has high value for the design of energetic fragment warhead.
