某车载炮上架刚度对弹丸起始扰动的影响

建立了某大口径车载炮弹炮耦合全炮动力学有限元模型，考虑了带膛线身管与弹丸的接触碰撞，通过数值计算得到了上架刚度对弹丸起始扰动的关系。分析结果表明，上架刚度与弹丸起始扰动并非单一的线性关系，且并非上架刚度越大对弹丸起始扰动越有利。

Impact of Top Carriage Stiffness of Vehicle-Mounted Gun on Initial Projectile Disturbance

Considering the contact collision between the rifled tube and projectile,a dynamic finite element model based on projectile-barrel coupling of a towed vehicle-mounted gun was established.The relationship of the stiffness of the top carriage with the initial disturbance of the projectile was obtained by numerical calculation.The results show that the stiffness of the top carriage and the initial disturbance of the projectile are not a linear relationship,and the higher the stiffness of the top carriage,the worse the initial disturbance of the projectile.
