摘要
针对弹体在斜侵彻仿真时不能准确获得弹体每一时刻的弹道偏转角度,并且只能获得弹体沿坐标轴方向的过载曲线,而不能获得弹体沿轴向和径向过载曲线的问题,提出弹体斜侵彻弹道偏转曲线及轴向过载计算方法。首先,需要完成弹体斜侵彻靶标的动力学仿真计算,获得弹体沿坐标轴方向的过载曲线及弹体上沿弹体轴向方向任意两点的位移曲线;然后,利用以上数据计算出弹体斜侵彻过程中的弹道偏转曲线及弹体沿轴向和径向的过载曲线。计算结果表明,该方法可以较为准确地计算出弹体斜侵彻靶标过程中的弹道偏转曲线及弹体沿轴向和径向的过载曲线。
In response to the problem that the trajectory deflection angle of the projectile at each moment cannot be accurately obtained during oblique penetration simulation,and only the overload curve of the projectile along the coordinate axis direction can be obtained,and the overload curve of the projectile along the axial and radial directions cannot be obtained,this paper proposes a method for calculating the deflection curve and axial overload of the projectile s oblique penetration trajectory.Firstly,the dynamic simulation calculation of the projectile s oblique penetration target needs to be completed,Obtain the overload curve of the projectile along the coordinate axis direction and the displacement curve of any two points along the axial direction of the projectile on the projectile,and then use the above data to calculate the ballistic deflection curve of the projectile during oblique penetration,as well as the overload curve of the projectile along the axial and radial directions.The calculation results indicate that this method can accurately calculate the ballistic deflection curve and the overload curve of the projectile along the axial and radial directions during the oblique penetration of the target by the projectile.
