Because of the problem about fewer to develop the research on numerical simulation of the function process of the energetic material in energetic device, the study was make here on the optimize design technical with numerical simulation for the explosive tank. The function processes of two styles explosive tank were numerically simulated with finite element code LS-DYNA in the paper. The analysis was down on the acting process of explosive in the tank, and the study on the stress distribution and the transformation of the tank wall at different moment were down and just as to the position of the maximum stress and the transformation. Upon this the optimize structure style was get through to compare the stress and transformation of two structures. On the basis of above, the need of developing researching faction was proposed. It was indicated that this method in the thesis not only to promote the study and manufacture of the energetic structure from the engineering estimating or testing manufacture to the optimize design technical with numerical simulation, but also to give the exact result of the stress distribution and the deformation of the explosive tank after working.
