Abstract: A method to acquire different blast waves is proposed. The geometrical models of the loading area of shock wave and air basin are established using SolidWorks, and then are divided to the structured grids by using Hypermesh. Material parameters and equation of state are assigned to the model. The curve of internal energy per unit volume and time is calculated with FORTRAN program and revised with the modified formula, then imported into the loading area of shock wave. The required shock wave is acquired by use of finite element program LS-DYNA. The proposed method can used to simulate the dif-ferent blast waves with error of 1.0%. The method provides an effective route for research on blast injury.
