摘　　要：基于动力有限元方法,确定炸药、空气和靶板的本构模型和状态方程参数,建立了爆炸波对四边固支靶板冲击的数值模拟模型,得到了靶板的凹陷损伤变形形式。爆炸波超压、靶板塑性变形模式以及靶板中心挠度的数值模拟结果与理论计算及相关试验结果吻合较好,验证了模拟方法和模型参数的准确性。Based on the dynamic finite element method and defining the parameters of detonator, air and target board, the simulation model of blast impact on the target board with rivet in the border was built. The board deformation was simulated. The simulation results of blast wave overpressure, the board plastic deformation and the camber of the board center are consistent with theoretical analysis and experiments, the simulation method and parameters are proved to be reliable and helpful for researching the equipment structural impact damage caused by blast.
