In the past, in all the calculations of nonlinear response of thin cylindrical shell under axial dynamic load, the effect of mass at the loading end of the shell was neglected.
圆柱薄壳受有轴向动力载荷作用的非线性响应计算中，以往忽略载荷作用端质量的影响。

The secondary parts such as radial sluice gate and its stand were neglected, the number of elements were decreased and the abnormal stress caused by improper loading were avoided in this method.
