摘　　要：针对火炮弹道计算中难以合理考虑空气阻力影响的问题,提出了一种基于射表数据合理考虑空气阻力影响的弹道仿真分析方法。通过对火炮射表数据分析,将空气阻力分解成水平和垂直2个方向,结合典型空气阻力理论模型,利用多项式拟合得出水平和垂直2个方向上的空气阻力所产生的加速度与速度的关系式,从而建立了一种基于射表数据的空气阻力模型。通过时间离散分析,推导并得出考虑空气阻力影响的火炮弹道计算方法,并通过仿真试验证明了该方法的正确性及有效性。As to the problem that it is difficult to consider the influence of air resistance in computing artillery ballistic trajectory rationally,a numerical analysis method is proposed for artillery ballistic trajectory with the influence of air resistance considered based on firing table. In the method,the firing table is analyzed carefully,and the air resistance is resolved to horizontal and vertical direction.Then,the formula for expressing the connection between the acceleration caused by air resistance and the velocity is obtained by polynomial curve-fitting based on the current classical theoretical model of air resistance. The method is realized by time discrete analysis to compute the artillery ballistic trajectory effectually with the influence of air resistance considered. Finally,the method proposed in this paper is proved to be correct and effective by simulation test.
