Abstract:	To meet the recoil requirements of practical electromagnetic guns, a new type of spring hydraulic buffer is designed based on the characteristics of electromagnetic launch. In response to the characteristics of multi parameter input, multi objective optimization, and multi boundary constraints in the design of the rectangular cross section cylindrical spiral combination spring recuperator for buffers, the structural parameters and constrained boundary interval that determine the spring characteristics are analyzed, the optimization objective function is designed, and an improved genetic algorithm is used to seek the optimal solution of the spring structural parameters. The results show that the shear strength of the inner and outer springs meet the standard, and the radial size of the outer spring decreases by 25.2%. The optimization method is applicable to the compact and lightweight design of spring hydraulic buffers with similar structures. The research results can provide an example for transplanting the recoil system of artillery to electromagnetic guns.
