General design principle of artillery for firing accuracy
文献摘要：
In this paper, based on the topological description method, the kinematic and dynamic equations of the projectile flight and projectile-artillery coupling system during the whole process of firing are con-structed. The factors that can affect the projectile burst points, namely the state parameters of the projectile on the muzzle and state parameters of the barrel muzzle, as well as the factors that affect the barrel muzzle state parameters, are analyzed. On this basis, the design principle of artillery firing ac-curacy is proposed. The error analysis and the corresponding inverse problem, the extraction method of key parameters affecting artillery implicated motion, the conformal and control method of rotating band are analyzed and presented. Finally, the presented method is verified through a vehicle mounted howitzer case, and the muzzle state parameter interval is obtained meeting the given firing accuracy. In addition, the sensitivity analysis of artillery parameters shows that the less the correlation between the parameters and the barrel, the less the influence on the projectile implicated motion. The analysis of the coupling effect between rifling and the rotating band shows that the uniform rifling is the optimal form for the conformal of the rotating band during firing.
