灰色系统理论在火炮内弹道性能变化量中的应用

Application of Grey-system Theory in Interior Ballistics Performance's Variety of Gun

为了研究火炮内膛质量状况与内弹道性能改变量之间的不确定相关性,提出采用灰色系统理论进行分析的方法,并建立了GM(1,N)计算模型,通过利用该模型对某大口径加农炮进行计算,结果表明:弹丸膛口速度计算值与实测值的相对差小于0.3%,膛压的相对差小于2%。

In order to investigate the uncertain relationship between the quality of internal barrel and the interior ballistics performance of a gun, the grey-system theory is used. Corresponding GM（ 1, N） numeration model is put forward. One large caliber cannon is analyzed by the model. The results show that the relative difference of numeration data and testing data of the projectile muzzle velocity is less than 0.3 %, and that of the maximum pressure in chamber is less than 2 %.
