摘　　要：聚脲弹性体具有良好的力学性能,喷涂于结构上能够提高其防护性能。为研究聚脲喷涂钢板结构靶板的抗爆性能,运用数值计算与试验研究方法,对聚脲弹性体-钢板夹层结构进行多种工况下抗爆性能研究。主要分析靶板的变形特点与吸能特性,并选用2种不同的聚脲夹层靶板对数值计算结果进行验证。结果表明:靶板在抗爆过程中,聚脲弹性体的存在不仅能吸收大量的能量,而且能抑制靶板发生大变形;为提高靶板抗爆能力,防止破片产生,其面板与背板需要有较好的强度与刚度。Polyurea elastomer has good mechanical properties, and its protective properties can be improved by spraying on the structure. In order to study the anti detonation performance of polyurea coated steel plate, numerical simulation and experimental research were conducted to study the anti detonation performance of polyurea elastic steel sandwich structure under various working conditions. The deformation characteristics and energy absorption characteristics of the target plate are analyzed, and two different polyurea sandwich plates are chosen to verify the numerical results. The results show that the target in the explosion process, the existence of polyurea can not only absorb a large amount of energy, but also can suppress target large deformation; in order to improve the target antiknock ability, prevent the fragments, the panel and the backboard need to have good strength and stiffness.
