某型坦克底盘线振动对行进间射击精度影响机理研究

Research on the Influence of Linear Vibration of a Tank Chassis on On-the-move Shooting Accuracy

针对某型坦克高速行进间射击精度较低的问题,从底盘线振动的角度分析了炮弹出膛的横向速度、瞄准系统成像质量、乘员观瞄操纵效能三方面的影响因素,并结合实车试验数据逐一研究了每个因素对射击精度的影响。研究结果表明:底盘线振动引起的横向射击偏差较小,不足以引起射击精度的大幅降低;底盘线振动虽然对瞄准镜成像质量虽然有一定的影响,但基本不会影响观瞄效果;而由于乘员乘坐位置线振动较大,乘员的乘坐舒适性较差,使其难以精确操纵瞄准设备,从而影响观瞄效果。因此,车辆底盘线振动对坦克装甲车辆射击精度的影响主要表现在对乘员乘坐舒适性的影响上,乘员舒适性较差是限制行进间射击精度的重要原因。

Three factors leading to the lower shooting accuracy for a tank moving at a high speed are analyzed based on the linear vibration of its chassis. The efects of the factors on the shooting accuracy are studied from the real test data. The research result shows that the lateral shooting deviation caused by the linear vibration of chassis is too small to reduce the shooting accuracy significantly. Although the linear vibration of chassis has some impact on the imaging quality of sighting telescope,it basically does not affect the sighting effect. Since the linear vibration of crew seat is larger and its ride comfort is poor,it is hard for the crew in the tank to precisely manipulate the sighting telescope,and then the sighting effect would be affected. Therefore,the influence of the linear vibration of tank chassis on the shooting accuracy is mainly through its impact on the ride comfort,and the ride comfort is an important reason of affecting on-the-move shooting accuracy.
