摘　　要：用ADAMS软件建立旋转弹丸的仿真模型,基于翻转力矩矢量垂直于阻力面的特性给出了惯性坐标系中翻转力矩矢量分量的表达式,通过FORTRAN子程序实现了翻转力矩的作用。然后用仿真模型对各种转速和各种翻转力矩幅值情况下的弹丸陀螺稳定性进行了仿真实验,研究结果对弹丸的稳定性设计和研究具有参考价值。A simulation model of a spinning projectile is created using ADAMS. The component formulas of the overturning moment vector in global system are derived from the perpendicular relationship between the overturning moment vector and the resistance side of the projectile, and a FORTRAN subroutine is used to implement the overturning moment action. The gyro stability of the spinning projectile is simulated in ADAMS while the projectile under several different rotational speeds and overturning moments. The study results have reference value for the design and research on projectile stability.
