| 摘 要： | 为了研究复合结构中爆轰波传播速度和曲率的关系,利用通用有限元程序AUTODYN对钝感复合装药结构单点起爆的爆轰效应进行了数值模拟。分析说明了不同尺寸的装药结构爆速和曲率的对应变化情况,根据曲面爆轰波曲率和爆速的线性近似关系,描述了复合装药药柱的爆速与曲率的关系方程,并拟合得到了相关参数。

| Abstract: | In order to study the relationship between detonation velocity and curvature in the composite charge structure,the current finite element program AUTODYN was used to simulate the detonation effect of the composite structure of insensitive ammunition by single-initiation position.The corresponding change situation between detonation velocity and curvature of different dimension charge structure was analyzed and explained.According the linear relationship approximately between the curvature of the curved surf... |
