| 火炮在射击前必须先进行瞄准。所谓的瞄准，就是赋予炮膛轴线以设计所必需的正确位置，使射击时的平均弹道通过预定射击点的动作过程。完成瞄准操作的装置称做瞄准机。火炮瞄准机是火炮随动系统的一个组成部分, 它由动力、传动机构与辅助装置组成。瞄准机设计的好坏直接影响到火炮火力的机动性, 由于火炮火力的强弱不仅取决于火炮的威力, 而且与火炮所具有的火力机动性有着密切的联系。也就是说: 威力强大的弹丸,必须迅速准确地命中目标, 才能先发制人地消灭敌人, 主动完成射击任务。 瞄准机包括高低机和方向机。通过高低机来操纵起落部分绕耳轴旋转赋予炮膛轴线的高低角，成为高低瞄准。通过方向机操纵回转部分绕立轴旋转赋予炮膛轴线的方位角，成为方向瞄准。59546 毕业论文关键词 瞄准机 高低机 瞄准速度 设计 Title 35mm automatic assault gun -- laying mechanism Abstract Artillery must first be to aim at in front of the fire. The aim, the bore axis is endowed with design required correct position, make the shot when the average trajectory through due to shooting point of action process. To complete the target operating device as the target machine. Artillery gun aiming machine is part of a servo system, which is composed of power, transmission mechanism and auxiliary device. Aiming at the machine design will have a direct impact on the mobility of artillery fire, the artillery fire not only depends on the power of the gun, but also has a close connection with the gun has the firepower mobility. That is to say: powerful projectile, must quickly and accurately, from hitting their targets, to preemptively to destroy the enemy, take the initiative to finish tasks. Aim at machine including height and direction. Manipulation of ups and downs section by elevating circles trunnion bore axis, given the high and low Angle, be aimed at. Manipulation by the direction machine rotary body vertical shaft rotate the gun axis, given the azimuth, become target direction.
