坦克炮总体结构参数分析

ANALYSIS OF THE STRUCTURAL PARAMETERS OF TANK GUN

影响坦克炮射击精度的主要因素之一是火炮振动 ,起关键作用的振动分量是在弹丸出炮口瞬间炮口振动角位移和横向线速度。为提高坦克炮射击精度 ,本文推崇“对称布置”和“初期自由后坐”的总体设计思想 ,使火炮射击时炮身和摇架所受的力矩尽量减小 ,同时使炮塔和车体在弹丸出炮口前的受力也尽量减小 ,从而减小了炮身的振动 ,也减小了炮塔和车体的振动 ,这对提高坦克炮射击精度将是十分有利的。本文运用动力学分析计算方法 ,阐明有关总体结构参数对坦克炮射击精度的影响。

Vibration of tank gun in the process of firing is one of the main factors that affect its firing accuracy, especially the instantaneous angular motion and the instantaneous linear velocity at the point of gun muzzle when the projectile leaves the barrel bore. To increase the firing accuracy, emphasis is laid on the design concepts of 'mounting two symmetrically arranged recoil brakes' and 'free recoil before projectile leaves the barrel bore', in order to decrease the interference forces and moments affecting the weapon system before projectile leaves the barrel. Method of dynamic analysis and calculation is used to explain how structural parameters affect the firing accuracy of a gun.
