摘要
对充液充压薄壁圆管侧向受平头及半球头弹体冲击问题进行了实验研究及计算机模拟 ,获得了薄壁圆管变形及破坏模态 ,实验观察到临界破坏速度随内充介质压力的增加而减小 ,而计算机的动画给出了圆管变形及破坏的发展过程。计算结果与实验测量结果相比较 ,其一致性是令人满意的。
Impact test was conducted in which pressure pipelines were struck by blunt and spherical projectiles. The computer simulations are also carried on the same time. The experiments show that the ballistic limit decreases with increase in the pressure of water. The procession of failure model and dynamic deformation was given by computer simulation. The consistency between experimental observation and numerical simulation is quite satisfactory.
