【摘要】 为了寻找发射目标角大小对火炮射角偏差的影响机理,该文结合实车振动试验,对试验数据进行了详细分析。研究表明:(1)高低角偏差几乎是底盘俯仰与侧倾这二种角振动引起的高低角偏差的线性叠加;方位角偏差主要是由车辆横摆角、车辆底盘俯仰运动与侧倾运动引起的方位角偏差组成。(2)高低角大小对高低角偏差几乎没影响;由侧倾引起的高低角偏差随着方位角的增大而增大,由俯仰引起的高低角偏差随着方位角的增大而减小。(3)由车辆底盘俯仰与侧倾运动引起的方位角偏差均随着高低角的增大而增加;由车辆底盘俯仰运动引起的方位角偏差随着方位角的增大而增加;由车辆底盘侧倾运动引起的方位角偏差随着方位角的增大而减小。这揭示了行进间射击过程中车辆底盘角振动与目标角大小对射击精度联合影响的机理。更多还原

【Abstract】 In order to find the influencing mechanism on gun firing accuracy resulting from tank chassis’ target angular in moving,the real vehicle test is carried out and test data are analyzed.Research results show that:( 1) Altitude angular deviation is equal to linear superposition of altitude angular deviation resulting from chassis’ vibration angular both in rolling and in pitching direction nearly. Whereas,chassis ’ yawing angular and azimuth angular deviations,which results from chassis’ angular vibration both in pitching and rolling,compose the azimuth angular deviation.( 2)The altitude angular almost has no influence on its deviation. But altitude angular deviation resulting from chassis’ pitching decreases with the rise of the azimuth angular,and altitude angular deviation resulted from chassis’ rolling would varys on the contrary.( 3) On the one hand,azimuth angular error resulting from both chassis’ rolling and chassis’ pitching increases with the increase of the altitude angular. On the other hand,azimuth angular error resulting from chassis’ pitching increases with the rise of the azimuth angular,but azimuth angular error resulting from chassis ’ rolling decreases on the contrary. These reveal the mechanism how shooting errors are influenced by moving tank chassis’ angular vibration together with target shoot angular values.更多还原
