××航炮的数学模拟

本文导出了规范化的二自由度自动武器系统动力学普遍方程和撞击公式,并将其推广到考虑炮架弹性的三自由度系统。在此基础上,编制了具有一定通用性和人机对话功能的数学模拟程序,应用该程序对××航炮进行了数学模拟,得出了武器系统结构参数和初始条件对运动、射频和后座力的影响规律,以及使后座力最小时可行的××航炮缓冲器结构参数的最佳匹配。本文还首次将功图应用于自动武器动力分析。

The Mathematical Analogue of a Certain Aircraft Gun

In this paper, the standardized general dynamic equations and imp-aet for mulas are derived which are suitable for the system of automatical weap-on with two degrees of freedom, and they are extended to the system with thr-ee degrees of freedom considering the elasticity of turret. Based on these egu-ations and formulas, the certain general mathematical analogye program is writ-ten which serve versat and man-machine dialogue functinos. When the programis applied to a certain aircraft gun, the influence laws of its strueture param-eters and initial conditions on the motion, fire frequency and recoil force areobtained, and the feasible best matching of the structure paramaters of a certainaircraft gun buffer is also obtained when the recoil force has its minimum. Th-is paper has first applied the work-diagram to the dynamic analysis of autom-atic weapon.
