基于耦合载荷作用下的圆柱壳动态屈曲研究

Dynamic Bucking of Elastic-Plastic Cylindrical Shells under Equal Radial Pressure and Torsion Impact Loads

研究了弹塑性圆柱壳在径向均布压力和扭转冲击载荷耦合作用下的动态屈曲问题,并采用ANSYS有限元方法对承受耦合载荷的圆柱壳进行了非线性屈曲模拟的计算。给出了圆柱壳在承受耦合载荷作用下的屈曲模态,分析比较了径向内、外压对圆柱壳扭转屈曲的影响。

The discussion of elastic-plastic dynamic bucking of cylindrical shells under the equal radial pressure and the torsion impact load was presented. The finite cylindrical shells are simulated for the dynamic buckling by the means of the finite software ANSYS. The data of the simulated results show the buckling modes of the cylindrical shells under the coupling loads. Finally,the effect of the internal and external pressure to this structure were analyzed and compared.
