摘要

建立了基座运动情况下弹炮系统的动力学方程和可以分别应用摄动法和数值法对方程求解的理论体系。讨论了炮弹出口速度、炮管仰角、基座加速度和炮管转动速度对炮管末端挠度的影响。算例结果表明,摄动法和数值法所得结果吻合得非常好,说明本文所建立的理论是可信的;炮弹出口速度、炮管仰角、基座横向加速度和炮管转动速度是影响炮管末端挠度的主要因素,并由此提出了一个基座运动情况下炮管末端挠度与这些主要因素间关系的解析表达式。

Abstract

In this paper the dynamic equations of the gun-projectile system and the corresponding two kinds of solving methods which are perturbation method and numerical method are established, respectively. After that the effects of the ultimate velocity of the projectile, the elevation of the gun, the acceleration of the barbette and the rotation velocity of the gun to the deflection at the end of the gun are studied. The numerical results of the two methods tally extremely well with each other ,which indicate that the theory established in this paper is reliable. Further research indicates that the main factors which influence the deflection at the end of the gun are the ultimate velocity of the projectile, the elevation of the gun, the transverse acceleration of the barbette and the rotation velocity of the gun and then a formulation of the deflection at the end of the gun about the forenamed factors under the barbette motion is put forward.
