摘　　要：针对因工艺导致的惯导陀螺存在不平衡质量的问题,讨论了转子在不平衡力偶作用下的运动特性。通过建立转子形体坐标系、惯性主轴坐标系以确定转子主轴相对惯性空间的方位,并分析了转子定向性的变化对惯导飞行控制过程的影响。同时,利用末制导炮弹刚体弹道模型进行了仿真,结果表明:转子铅垂方向以及水平方向的动不平衡角对末制导炮弹的射程和侧偏具有重要的影响。Aiming at the problem of unbalance in the inertial guidance gyro rotor, this paper discusses the special feature of motion of the rotor under the action of unbalanced moment, establishes the body coordinate system and inertia principal axis coordinate system to determine the direction of the rotor, and analyzes the influence of the directional variation of the rotor on the control progress of terminal guided projectile. The ballistic model of terminal guided projectile is used for numerical simulation. The results show that the unbalanced angle of the rotor has an important effect on the firing range and yaw of shells.
