| Abstract: | According to actual dynamic shock conditions of a lattice buffer device,the tests for the dynamic mechanics property of the relative materials were carried out by using SHPB(split Hopkinson pressure bar) test system and the associated mechanics property parameters were obtained.The computational models were established for fluid-solid coupling buffer device by using dynamic boundary and dynamic grid techniques.The collapsing tests for the buffer devices were carried out following the rules that the energy a... |
