摘　　要：现代战争要求榴弹炮具有准确修正射击的能力。为了提高榴弹炮的射击准确度,应用多体系统传递矩阵法建立了榴弹炮系统的发射与飞行动力学模型,计算了榴弹炮的射击密集度,仿真结果与实验符合较好。计算了不同射角下平均弹道的射程、最大弹道高与侧偏的斜率。建立了基于平均弹着点的射击修正方法。修正结果表明,该方法可有效提高榴弹炮射击准确度,为提高榴弹炮的射击精度提供理论依据与技术手段。The modern warfare requires that the howitzer should have the ability of firing correction.In order to improve the firing accuracy of the howitzer,the launch and flight dynamics model of the howitzer is established based on the multibody system transfer matrix method,and the firing dispersion of the howitzer is calculated. The simulation results are in good agreement with the experiment. The gradient of the range,the maximum trajectory height and the drift of the average ballistic trajectory are calculated at different firing angles. The firing correction method based on the impact point of mean is established. The results provide theoretical basis and technical means for improving the firing accuracy of the howitzer.
