| Abstract: | The mathematical model of fuzzy-robustness optimal design of the press-adjusting spring in an inserted overflow valve was established in order to find the maximal inherent frequency. The fuzzy factors and random factors were considered synthetically. This model was solved with Chaos-Genetic optimal algorithm. Academic analysis and design example show that the robustness of designed target can be improved by fuzzy-robustness optimal design, and the feasibility robustness of fuzzy restrictive conditions can be assured under the influence of controllable and incontrollable factors. The method of fuzzy-robustness optimal design is effective in improving design quality of inserted overflow valve. |
