摘　　要：为了研究火炮射击精度的影响因素,制订身管设计和制造的技术条件,根据实测的身管直线度误差和炮口角偏差,以计算机数值仿真技术为手段,分析了身管直线度误差导致的弹丸初速跳角散布大小及其对火炮最大射程地面密集度的影响。研究结果表明:弹丸初速跳角散布在-2～2 mrad范围内,这导致最大射程地面密集度由1/500降低为1/491;火炮初速跳角散布不是影响火炮最大射程地面密集度的主要原因。The study purpose of this paper is to study the factors influencing gun firing accuracy and to work out technical specifications for gun design and manufacture standard. According to barrel straightness error （BSE） and muzzle angle error, the jump-angle dispersion of initial velocity caused by BSE and the effect of BSE on ground dispersion of extreme range of projectile were analyzed by numerical simulation technique. The result shows that within the velocity jumpangle dispersion -2-2 mrad, the extreme range ground dispersion is reduced from 1/500 to 1/491. The initial velocity jump-angle dispersion is not the principal factor influencing gun firing accuracy.
