Abstract:

A mathematical model of occupant restraint system of a mini-bus van in frontal impact based on software MADYMO was established. Based on that, the optimization process was conducted by conjuncting design of experiments, response surface method and robust probabilistic optimization design. The chosen design variables during this optimization were webbing stiffness, upper slipping position of the seat belt, the tearing force and the adding length. By applying the robust design, this method can reduce the sensitivity of design point and control the fluctuation of the design objects. Consequently, this will conduce to improve the quality of the products. The analysis results indicate that this method realizes the optimization of the design object, and enhances the reliability of the design parameters and the robustness of the objective function, which will make significant improvement in the engineering applications. 

Key words: restraint system, design of experiment, response surface method, robust probabilistic optimization
