| Abstract: | Firstly a mathematic model is established for optimizing design of antenna structure's continuous variables under intense explosion shock wave loading, which is constrained by structure's accuracy and stress. Then according to the characteristics of structure material the variables are treated as discreteness, and the model is modifie for discrete variables. Finally by taking an optimum design method of discrete variables the discrete compound shape method, the optimizing calculation of 8m antenna is carried out. Results indicate that the optimized antenna weights only 40% of the initial un optimized one. |
