Abstract: :Parameter design is the most important stage in product robust design. To reduce product quality fluctuation and improve its disturbance resistance capability, a percentile-based parameter design optimization model was proposed considering both the design objective robustness and design constraint robustness. A solution framework to this model, which combined the ideal point approach with the most probable point based percentile search algorithm, was also presented to guaranteethe efficiency and flexibility of the model. A case study of a diaphragm spring in automobile clutch was applied to suggest the effectiveness and practicability of the proposed approach.
