Abstract: A mathematical model of multi-objective optimal design based on robust was established in order to find the least change spring's stiffness, maximal inherent frequency and minimal spring mass. Random factors in the optimal design were considered synthetically. The mathematical model was compiled into a programmer and computed into the result in MATLAB. A hydraulic valve spiral spring design example shows that the designed target can be improved by multi-objective robust optimal design and the dynamic response characteristics of the hydraulic valve were enhanced in a certain extent.
