摘要随着现代战争的发展，筒式发射技术为了满足不同作战需求，衍生出了多种作战功能，对现代战争起到了重要作用。为了研究筒式发射系统的工作原理，在查阅了大量国内外有关文献后，针对筒式发射系统的特点，对其内弹道过程进行了数学建模及仿真计算。首先分析了系统结构特点和发射工作过程，基于经典内弹道理论进行简化，对发射系统的内弹道过程进行了数学建模。接着在 Visual Basic 语言环境下编制筒式发射系统发射过程内弹道计算程序，运用经典Range-Kutta 方法进行数值计算，实现了筒式发射系统内弹道过程的模拟。然后计算了在给定条件下的发射过程，并对数据进行系统分析，总结出装填条件对筒式发射内弹道性能的影响规律及特点。计算表明，所建模型合理。最后，针对装填参数和结构参数对内弹道性能的影响进行了分析， 为筒式发射结构及装填参数设计提供参考。61030

Title  Interior ballistics numerical simulation of cylinder launching 
Abstract With the development of the modern  war, many more operation functions have been derived from the cylinder launching technology to satisfy different operational requirements. In this paper, the interior ballistic process of the cylinder launching system undergoes a mathematical modeling and simulation calculation to reveal  its working principle. The first attention is paid to the structural characteristics of the launching system and the launching process. Then the simplification based on the classical theory of interior ballistics leads to  a mathematical modeling. The ballistic calculation program during the launching process is composed in the VB language environment and the numerical calculation is realized according to the classical Range-Kutta formula. In this way the ballistic process simulation of the cylinder launching system is achieved. With the simulation of launching process under given conditions and a systematic analysis of the calculation data, a regular pattern comes to light about how the loading conditions influence the ballistic properties of the cylinder launching system. The model proves reasonable and feasible after calculation. In the end, another analysis is conducted of the influence of loading parameters and structural parameters on the ballistic performance, aimed at  providing some parameter reference to the structural and loading design of the launching system.
