摘要
本文研究了球弹性壳在撞击载荷作用下的动态行为。基于Ｐｏｇｏｒｅｌｏｖ的曲面弯曲理论，给出了在任一时刻的壳体变形能的近似表达式，通过能量守恒，得到了描述受冲击后壳体运动控制方程，采用Ｒｕｎｇｅ—Ｋｕｔｔａ方法，求解了此方程，并给出了冲击力，窝陷半径随时间变化的关系曲线。
This paper studies the dynamic behaviour of elastic spherical shells by a flat-nosed missile.Baded on Pogorelov’s bending theory of surfaces,the approximate formulae of deformation energy of shell are derived at any time,By using the energy balance,the motion equations of shells are resulted.Finally,a comparison made between the numerical results and experimental ones indicates that the two groups of results are in comformity with each other.
