This paper presents the robust design and response surface method (RSM) based on finite element
analysis for the optimization design of metro handrails. The response surface can be created for each output
parameter. Sequential quadratic programming is used for the optimization of metro handrails. Taguchi design
is employed to investigate the sensitive controlling factors for the strength and mass of metro handrails, by
taking the material density, the column and cross bar thickness as controlling factors, and the acceleration, the
elastic modulus and the fluctuation of material density as uncontrollable factors. Then, the best combination of
controlling factors is found. The results by different methods show that the method of Taguchi design can improve
the robustness of the structural performance and reduce the mass.
