The erection of the solid rocket motor multi-casting system is optimized. The three-dimensional parametric model of the column is established, and the static analysis is carried out to determine the total deformation and the equivalent stress distribution of the hoisting column. Take the important dimensions such as shaft diameter and length of column as design variables, mass, equivalent stress and maximum deformation as target variables. The multi-objective genetic algorithm based on response surface is used to optimize the size of the hoisting column. The results show that after optimization, the overall quality of the column is 28.931kg, which is reduced by 6.16kg, which is 17.7% lower than the original plan.
