水下枪械内弹道基本方程组的建立及MATLAB仿真

摘要

介绍了水下枪械发射的技术特点，分析了水下枪械内弹道与常规枪械内弹道的差异，以弹丸和枪管内水柱作为受力体建立了水下内弹道的简化模型，推导出了水下枪械内弹道基本方程组。利用MATLAB软件对其进行仿真得到的 p-t，v-t，p-x曲线与实验所得到的曲线具有较好的一致性，为水下枪械的设计提供了一定理论依据。%This paper presents the characteristics of underwater gun's firing techniques and analyzes the difference between the interior trajectory of normal gun and that of underwater gun .The simplified models of underwater trajectory are established by regarding bullet and water column in barrel wholly as a force-acceptor ,and the fundamental equations suitable for calculation of underwater gun's ballistic characteristic are also deduced .By use of the software MATLAB ,the p - t ,v - t , p - x curves are obtained ,which are same as the experiment ones .This study offers the theory to design the underwater gun .
