摘　　要：为了研究柱形装药爆炸驱动破片速度变化,提出了一种新的计算破片初速度的方法;运用AUTODYN软件对典型炸药不同的装填比开展爆炸力学数值模拟研究,提取其数值模拟数据并基于冲量定理进行力学分析,将推导构建出一种计算柱形装药壳体速度的新模型与斯坦诺维奇理论模型进行对比分析;研究结果表明:提出的新模型考虑到材料属性,能更好地表征壳体的速度变化,对破片初速计算研究有一定的参考意义。In order to study the velocity variation of explosive fragments driven by cylindrical charges,a new method of calculating the initial velocity of fragments is proposed. AUTODYN software is used to study the numerical simulation of explosion mechanics for different loading ratio of typical explosives. The numerical simulation data is extracted and the mechanical analysis based on the impulse theorem is carried out. A new model for calculating the velocity of cylindrical charge shell is derived and the stanovich theoretical model is compared and analyzed. The results show that the proposed new model,taking into account the material properties,can better characterize the velocity variation of the shell,and has a certain reference significance for the calculation of the initial velocity of fragments.
