| 摘 要： | 以有限变形连续体的最小加速度原理为基础，导出了在任意位置受到横向集中动力载荷作用下的闭合圆柱壳的有限变形运动方程，该方程反映了膜力效应和转动惯性效应；推导过程直接、简便、不易出错，同时指出，所得到的控制方程对于描述有限变形的冲击动力学问题是适宜的。

| Abstract: | In this paper, the finite deformation equations of motion for a cylindrical shell, which is subjected to normal concentrated loading at arbitrary position, are derived by using the minimum principle in dynamics of elastic plastic continua at finite deformation, the effects of membrane force and the effects of rotatory inertia are reflected in the equation. It can be shown that the course of educing the equation is direct and straightforward, the error doesn't produce easily. The equations are fitting to represent the impact dynamic problem of finite deformation structure. |
