Impact of Traversing Mechanism Stiffness of Light Towed Howitzer on Initial Projectile Disturbance
为研究方向机刚度特性对弹丸起始扰动的影响,以某轻型牵引炮为例,建立了弹炮耦合全炮发射动力学有限元模型,分析了不同刚度下的弹丸起始扰动,在建立的弹丸起始扰动目标函数的基础上,研究了方向机刚度对弹丸起始扰动的影响规律.结果表明:随着方向机刚度的增大,弹丸起始扰动逐渐减小;该炮弹丸起始扰动随方向机刚度的变化呈现有利的变化趋势.
To study the impact of traversing mechanism stiffness on the initial disturbance of projectile,a light towed howitzer was taken for example,and the finite element( FE) model of projectile-barrel coupling dynamics was established to analyze the initial projectile disturbance under different stiffnesses. Based on the established objective-function of initial disturbance of projectile,the rule of the traversing mechanism stiffness affecting the initial projecti…查看全部>>
