摘要通过对弹丸在膛内运动以及火药燃烧特性的分析,建立了描述枪炮内弹道过程的物理模型。在合理的简化假设基础上,建立了描述经典火炮内弹道过程的数学模型,包括单一装药和混合装药条件下的内弹道模型。结合模型方程组为常系数微分方程组的特点,采用四阶精度龙格—库塔计算方法完成对模型的离散化处理。以 VB为基础,编制了基于对话框的可视化的通用内弹道的计算程序。程序中设计了合理的数据库接口,通过调用火炮弹道参量数据库和火药参量数据库,完成计算所必需的参量的输入,并能够根据需要修改对应的参量。通过软件的运行,能够完成对应口径火炮及装药条件的内弹道计算,并将计算结果进行存储和显示。61061

Title Guns interior ballistic calculation common software
Abstract Through the analysis on the characteristics of the movement of projectile in bore and gunpowder combustion, the physical model which describes the guns interior ballistic process is established and mathematical models are established based on the reasonable simplifying assumptions to describe the classic interior ballistic process, including the interior ballistic models under the conditions of single charge and mixed charge. According to the characteristics of the model equations for the constant coefficient differential equations, the model is discretized by using the fourth-order Runge - Kutta numerical method. The visual common interior ballistic calculation program based on dialog is compiled on the basis of VB. The reasonable database interface has been designed in the program so that the required parameters for the calculation can be input by calling guns ballistic parameters database and gunpowder parameters database and the corresponding parameters can be modified according to the need. Through the operation of the software, the interior ballistic calculation for the corresponding caliber gun and the charge condition can be complete and the calculation results can be stored and displayed at the same time.
