N2  - This paper aims to present a systematic approach to improve the design of an on-road bicycle frame which undergoes drop-mass impact test simulation. Performance measure of the frame is maximum permanent displacement (MPD) along the longitudinal direction of the frame, according to EN-14781 bicycle testing standard. The behavior of the frame impacted by a dropping mass is predicted by explicit dynamic finite element analysis. The innovative and integrated procedures composed uniform design of experiments, Kriging interpolation, genetic algorithm and Nelder-Mead simplex method are introduced in this study. Based on the numerical results obtained in this paper, MPD can be reduced by 11.7% after performing the uniform design of experiments and 13.3% after performing surrogate modeling and optimization. For the optimal design of frame, the most significant factor is TTT. Decreasing TTT is not beneficial for reducing MPD.<p /> <p>Language: en</p>
