Abstract
Five parameters of waterproof board( WB) for the SRM of some type of missile were investigated using artificial neu-ral network algorithm (ANN).The objective function employed in the present work was the max stress and the min mass of the SRM waterproof board which bears a hydraulic pressure.The deformation and the strain of the waterproof board under the force of 10 t at center position were obtained,and the correctness of the numerical simulation was verified by comparing to the experimental results. The objective function vs. design variables curves were plotted,and the parameters sensitivity analysis were carried out.Optimization can decrease the mass of the waterproof board effectively by 45. 59% compared to traditional methods. The results obtained can be used as a guidline for the optimal structure design of the SRM waterproof board.关键词
