For its requirements of insertion and withdrawal force, we would like to discuss the maximum of insertion and withdrawal force for the spring terminal. For the analysis in this thesis, first, we set insertion force and withdrawal force as the quality characteristics. Further, we set the factor that affects the quality characteristics as the length of spring teminal arm (L)、the length of a curve portion that connects the main body and arm of terminal (H)、the width of arm (W), and the gap that is formed between the spring terminal arms (D). The experiment was designed based on the 4 factors-3 levels Box–Behnken design, with ABAQUS software for finite element analysis simulations. Simulation result was used for setting up the model of the response surface of quality characteristic by the method of linear regression using the Minitab software.The simulation data obtained in this thesis were compared with experiments to verify their effectiveness and appropriateness. The standardized residuals of insertion force, withdrawal force and maximum von-Mise stress simulated by the regression model of response surface were within +/-3. Also, the error between the optimizations, determined by the simulation and response surface methodology, respectively, was around 2%. It proves the reliability for using response surface methodology in the application of spring terminals.
