1 引言为了提高弹药破片的杀伤威力,合理利用弹壳材料,破片预控技术得到了世界各国弹药界的广泛关注,并在一些弹药、战斗部设计中得到了应用。J·Pearson研究指出,爆轰波波阵面前进方向与刻槽槽面相互作用,槽的形状将直接影响试件的破碎特性,为验证爆轰波波阵面对不同位的刻槽面的作用和对试件的破碎影响程度,本试验设计了具有陡面和坡面刻槽
1 Introduction In order to improve the killing power of ammunition fragments and make rational use of the material of the shell, the pre-control technology of fragments has drawn the attention of the ammunition circles all over the world and has been applied in the design of some ammunition and warheads. J Pearson research pointed out that the direction of the detonation wave front interacts with the groove surface. The shape of the groove will directly affect the crushing properties of the specimen. In order to verify the effect of the detonation wave front on the groove surface of different positions Role and impact on the specimen crushing degree, the experiment designed with a steep surface and slope grooves
