摘要: 为了研究高速旋转稳定弹丸在飞行过程中的锥形运动规律,采用弹载地磁姿态测试方法,通过分析当地地磁矢量、弹丸速度矢量及弹轴地磁测试分量间的角度关系,构建高速旋转弹丸角运动规律及参数的测试模型。给出弹载地磁测试的试验方法,构建测试平台及相应的标定与校正设备,通过试验测试获得了地磁测试数据,完成了地磁测试数据的信号滤波与姿态解算,得到弹丸锥形运动的轨迹曲线。结合弹丸角运动模型对测试弹丸的角运动过程测试结果进行分析,进一步分解得到了弹丸进动、章动运动规律。分析结果表明弹载地磁测试与弹丸角运动模型可以相互支撑,能准确揭示高速旋转弹锥形运动的规律。

Abstract: In order to study the coning motion of high-speed spin-stabilized projectile during flight, the on-board geomagnetic attitude measurement method is used to build a test model. The angular relation among local magnetic vector, projectile velocity vector and projectile-axis geomagnetic component is analyzed. A test model for the angular movement and parameters of high-speed spin-stabilized projectile is built, an experimental method is proposed. The test platform and the calibration devices are constructed too. The on-board geomagnetic test data is obtained through experiment. Signal filtering and attitude resolving are conducted based on geomagnetic test data. The trajectory curve of projectile coning motion is got. Test results of projectile coning motion is anlyzed,and the laws of projectile precession and nutation motion are obtained. Analysis result shows that the on-board geomagnetic test method and the projectile angular motion model can be used accurately to reveal the coning motion law of high speed spin-stabilized projectile.
