【Abstract】 A multi-layer composite structure model composed soft high-strength steel,polyurea elastomer,aluminum foam and ultra-high molecular weight polyethylene was established. The different structures and thicknesses were analyzed by numerical simulation. The central displacement, absorbed energy and acceleration response of the multi-layer composite structure under distribution were obtained,and the composite structure with the best blast-resistant performance was obtained. Finally,the blast-resistant performance of the composite structure was verified. The results show that the numerical simulation analysis method can be used for the optimization design of multi-layer composite blast-resistant structure. The blastresistant test of the optimal multi-layer composite structure is preliminary and provides technical support for the subsequent research of related products.更多还原
