Reliability-based robust design optimization of vehicle components, Part I: Theory

Abstract

The reliability-based design optimization, the reliability sensitivity analysis and robust design method are employed to present a practical and effective approach for reliability-based robust design optimization of vehicle components. A procedure for reliability-based robust design optimization of vehicle components is proposed. Application of the method is illustrated by reliability-based robust design optimization of axle and spring. Numerical results have shown that the proposed method can be trusted to perform reliability-based robust design optimization of vehicle components.

Key words： vehicle components; reliability-based design optimization; reliability-based sensitivity analysis; multi-objective optimization; robust design
