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.
