Abstract
In this study, we present a new practical optimum design method that consists of two steps: finite element analysis (FEA) and design of experiments. The design of experiments is used to generate approximate evaluation functions for controlling the behavior depending on the changes in the design variables of an object structure by finite element analyses. Here, we used a design of experiments to determine the optimal combination of design parameters in the texture analysis for friction coefficient reduction. The effects of the design variables can be calculated based on an orthogonal array of design variable combinations. The approximate evaluation functions were then generated by these effects based on the analysis of variance. The proposed method was found to be an effective and powerful tool for the optimum design of various practical design problems.
