【摘要】：针对带前舱弹体斜侵彻硬目标靶体的动态力学响应问题,建立了变截面刚度自由梁在横向及轴向载荷交互作用下的动态力学响应模型,分析了带前舱弹体斜侵彻硬目标时的动态响应特性,得到了前舱破坏对弹体着靶姿态角的变化规律,结果表明,前舱的量纲一长度、前舱与弹体连接刚度/前舱截面屈服模量与弹体的偏转角正相关.
[Abstract]:Aiming at the dynamic mechanical response of projectile with front cabin penetrating hard target, the dynamic mechanical response model of free beam with variable section stiffness under the interaction of transverse and axial loads is established. In this paper, the dynamic response characteristics of projectile with front cabin when it penetrates hard target are analyzed, and the change rule of attitude angle of front cabin damage to projectile body is obtained. The results show that the dimensionality of front cabin is one length. The connection stiffness of the front cabin and the projectile body / yield modulus of the front cabin section are positively correlated with the deflection angle of the projectile.
