The structural compensation ability of Ω spring set,as an important component of ship seal device,directly affects the sealing effect of ship seal device.Based on zero-order optimization method,multi-parameter optimization of the Ω spring set was conducted with the design variables of the characteristic thickness,width,and the radiuses of both the middle and top circles.The responses of various design parameters and the optimal solution of maximum radial stiffness were analyzed.In conclusion,the radial stiffness increases by 11.5% after the optimization.Moreover, making the harmonic response analysis of Ω spring set before and after the optimization respectively,the results verify the effectiveness of Ω spring stiffness optimization to modify its frequency compensation ability,and thus improve its structural compensation ability.
