摘　　要：弹丸6自由度运动微分方程计算是外弹道数值计算理论中的一个重要内容。其中绕心运动的攻角微分方程在稳定飞行条件下其解为衰减的振荡曲线，因而方程数值解的收敛性、稳定性较差，求解较为困难，且计算时间很长。本文以尾翼稳定弹为例，对其刚体弹道运动微分方程的求解技术作了探讨，分析了尾翼弹飞行稳定的条件。Numerical calculation of 6-D differential equations for the motion of projectiles is of importance in exterier ballistics. The solution for the angle of attack is a damped curve of vibration under the condition of a stable flight,thus the convergence and stability of such a numerical solution can not be satisfactory and it is often difficult to solve. In addition,the calculation takes a long time.Taking the fin-stabilized projectile as an example,this paper discusses the numerical techniques to solve a set of 6-D differental equations of motion and analyses the conditions of stable flight for this kind of projectiles.
