车—炮系统动力学分析

Dynamatic Analysls of Vehicle-Gun System

该文在广泛参考现有车—炮系统动力学模型的基础上,建立了停止间射击时车—炮系统平面七自由度动力分析模型。采用经典的Lagrange方法建立系统的运动微分方程。编程求解了系统主要受力及运动参数,为火炮动力特性及精度分析提供了数据。本模型及计算机程序可计算不同射角、不同弹种,并改变火炮各种参数对火炮动态性能的影响。

By extensively studying the existing dynamatic modelsof the vehicle--gun system, this paper presents a 2-D model with sev-en-degree of freedom of the system in which the vehicle is initially atrest and the gun is firing. The differential equations about the systemmotion are established with the aid of Lagrange method. Then a com-puter programe is given through which the major parameters of thesystem motion and the action between different components can becalculated. By changing various parameters. of the gun in this modeland program, the influence of these parameters can also be studied onthe dynamatic characteristics of the gun.
