摘要
为确定某大口径炮射弹药的最大射程角及其与初速度的关系,采用解外弹道方法进行研究。给出了弹丸在直角坐标系中以时间t为自变量的运动方程组,在MATLAB\SIMULINK中建立了上述方程组模型,计算了射程角为50°～55°时的射程,拟合了射程与射程角的关系曲线,给出了上式关系曲线的等式方程。并计算了该炮射弹药在一系列不同初速下的最大射程角,拟合了最大射程角与初速的关系曲线,从拟合的曲线可以看出:最大射程角随着初速的增加而增加。实际结果证明,该方法具有方便、快捷的优点。
For researching the relationship between the ranges and the range angles of certain type large caliber cartridge,research it with the way of solving exterior ballistic.Giving the movement cartridge controlling equations under right angle reference systems,which takes t as the independent variable,and also sets up its model based on MATLAB／SIMULINK software,then calculates the ranges which belongs to the range angles range 50°～55°,drafts the curve relation between the ranges and the range angles.Calculate the range angles in different muzzle velocities,and also draft the curve relation between range angles and muzzle velocities.From the curve,it shows that the maximum range angle is increased when muzzle velocity is higher.The test result shows the method is convenient and easy.
