摘要：
The drop process of an energy-absorbing container was simulated by air gun impact test, and the forward and 30° oblique impact experiments of the scale model were carried out. The numerical analysis for the model experiments was conducted to obtain the stress distribution and plastic deformation of the energyabsorbing container model in the impact process. And then the calculation and experimental results were compared. The results show that the energy-absorbing container absorbs energy mainly by the plastic deformation of cushion wood and the plastic hinges produced by the buckling of outer steel shell during impact, and its plastic deformation mainly concentrates at the impact end, while no plastic deformation is found far away from the impact end. In simulations, the compressive stress-strain curve of the wood in texture direction can be used to simulate the drop impact process of energy-absorbing container. © 2019, Editorial Staff of EXPLOSION AND SHOCK WAVES.
