摘　　要：分析和总结充液圆柱壳承受轴压作用时发生屈曲、后屈曲及破坏的规律和特性。通过实验观察充液圆柱壳的屈曲及后屈曲模态,进行不同高度、不同厚度的对照实验,并应用ANSYS/LS-DYNA软件进行模拟仿真,对比数值解与实验解。The laws and specific properties of nonlinear buckling,post buckling and destroy on cylindrical shells fully filled with liquid under axial compression were studied. Through a lot of experiments,the fluid-filled cylindrical shell buckling and post buckling modes were observed during the experiments,and a number of control experiments under different height and different thickness were done. Finally,the experiments were simulated by ANSYS / LS-DYNA software and the numerical solutions and experimental solutions were compared.
