摘要:

以陆地枪械发射内弹道方程组理论为基础，结合水下聚能剪切器动作的技术特点，对动刀运动的能量转化机理和刀架内部组件的动力学响应进行了综合分析，建立归一化数学模型，用于内弹道参量变化特性曲线的数值计算。通过对某型号水下剪切器内弹道仿真求解，定量分析了各参量变化过程，论证了短行程聚能剪切方案的可行性，为后继内弹道设计及装药参量的优化奠定了理论基础。

Abstract:

Based on the interior ballistic equation theory，with the technique characteristic of underwater shaped charge cutter movement，the normalized mathematical model was established，by comprehensive analyzing energy conversion mechanism of moving cutter and dynamic responses of modules in cutter foundation.The interior ballistic equation of the some underwater shaped charge cutter was solved，with quantificationally analyzing the changing process of the parameters，proving the feasibility of short stroke shaped charge cutting programme，and laying the theory foundation of designing interior ballistic and optimizing the ammunition parameters.
