摘　　要：对某小口径旋转稳定弹的质心运动和角运动特性进行了研究,建立了包含有控制项的六自由度刚体弹道模型,分析了无控时初速和起始扰动对角运动的影响,研究了不同初速下控制力作用在不同位置时弹丸的质心运动特性以及控制力大小、方向和作用位置在不同弹道段对角运动的影响。仿真结果表明:控制力作用在压力中心后,弹丸质心运动与控制力同向,作用在压力中心前质心运动与控制力反向;角运动在极限圆形成之前受控制力影响较大。研究结果对后续开展小口径旋转稳定弹的控制方案设计有参考价值。To understand the ballistic characteristics of small-diameter spin-stabilized projectiles under control,the characteristics of centroid motion and angular motion were studied.A six-degree-of-freedom rigid body ballistic model with control terms was established.The influence of initial velocity and initial disturbance on the angular motion was analyzed when it’s uncontrolled.The characteristics of the projectile centroid motion with control forces at different initial velocities and points of application were studied,as well as the influence of the magnitude,direction and points of the control forces on different ballistic segments to the angular motion.The simulation results show that the centroid motion of the projectile was in the same direction as the control force when the control force is applied behind the center of pressure and the centroid motion was opposite to the direction of control force when it’s applied in front of the center of pressure.The angular motion was greatly affected by the control force before the formation of the limit circle.The research results have certain reference value for the subsequent control scheme design of small caliber spin-stabilized projectile.
