摘　　要：为了研究异型弹运动姿态控制对其运动的稳定性和侵彻效果的影响,采用LS-DYNA3D软件,对不同着角及攻角异型弹弹道轨迹的趋势和规律问题进行了数值模拟计算。结果表明:侵彻着角越大,对异型弹的姿态俯仰角的影响越小;大攻角对异型弹姿态俯仰角的影响远大于侵彻着角变化对姿态俯仰角的影响,且攻角的方向起着重要作用;存在着角和攻角最佳组合,使得侵彻效果最好。研究结果为弹道控制设计提供依据和借鉴。To study the influence of the motion attitude of special-shaped projectile（SSP）on its stability and penetration effect,the tendency and regularity of trajectory of SSP with different obliquity and angle of attack were numerically simulated by using LS-DYNA3 Dsoftware.The simulation results indicate that the larger the pitch angle,the smaller the effect of the attitude angle of projectile;the effect of high attack angle on attitude angle of SSP is much greater than that of pitch angle change,and the direction of attack angle plays an important role.There is the best combination of pitch angle and attack angle so that the penetration effect is the best.The study on the motion stability of SSP can provide the basis and reference for trajectory control design.
