• In order to explore the numerical analysis method suitable for dynamic responses of aviation aluminum alloy plates under explosive impact loads, numerical simulation of the aluminum alloy plate under explosion was carried out with the LSDYNA explicit dynamic analysis software. Influences of different advection steps of the arbitrary LagrangianEulerian method (ALE), the fluidstructure coupling mode, the number of coupling points, the mesh size and the finite element type on the numerical results were detailedly studied. Comparisons between the numerical results and the test results show that the dynamic responses of the aluminum alloy plate under explosive impact loading can be calculated accurately with the van Leer+HIS advection step, the penalty coupling method, 3 coupling points, a ratio of 2∶1 between the structure mesh size and the air mesh size, and the Shell163 element. Simultaneously, the calculation efficiency can be improved and computation time saved.
