摘　　要：在经典内弹道理论的基础上建立了某迫榴炮的内弹道数学模型并利用数值解法求解,得到压力、速度与时间及行程的关系曲线,分析了装药量、弹重、炮管间隙及药室容积等因素对内弹道性能的影响;基于最优化理论,对内弹道装药进行优化设计,选用复合形法,编制程序求解并对优化结果进行分析;对迫榴炮的研制与设计具有一定的指导意义。Based on the classical theory of interior ballistics, an interior ballistic mathematical model of a mortar-howitzer was established. The numerical solution method was used to solve the interior ballistic mathematical model, and the curves of pressure, velocity with stroke and time are obtained. The impact of changes in loading capacity, ballistic weight, banal clearance, and chamber volume on the performance of interior ballistics were analyzed. Based on the optimization theory, an optimization design problem for interior ballistics was proposed. The complex shape method was selected and the program was compiled to solve the problem. The optimization results were analyzed. The calculation results and analysis are of great significance to the research and design of the mortar-howitzer.
