| 摘 要： | 当圆柱壳承受径向脉冲载荷时，如果其径厚比大于一特定值，圆柱壳将产生弹性动力屈曲．本文根据有关实验结果，假定变形模态，采用Ｌａｇｒａｎｇｅ方法分析了有限长薄圆柱壳（ａ／ｈ＝４８０）在余弦冲击载荷作用下的弹性脉冲动力屈曲．导出了动力屈曲方程组，借助数值方法求解方程，并与有关计算结果进行了比较．

| Abstract: | When a cylindrical shell is subjected to dynamic impulsive loading in radialdirection and the ratio of radius-to-thickness exceeds a special value, the cylindrical shell will produce elastic dynamic buckling. This paper which is based onthe rosults of some relative experiments, assumes deformation mode and utilizes Lagrange method to analyse the elatsic pulse buckling of a thin cylindrical shellwith a finite length under a cosine impulse. The dynamic buckling equations aredenyed and solved by numerical method. The results of calculation are compared with some relative calculation results obtained by other authors. |
