Abstract
Safety factor is widely introduced to improve reliability of mechanical products / structures. However, since compliant mechanisms are quite different from traditional mechanisms, it is difficult to configure safety factor empirically. In order to design reliable compliant mechanisms, we extend optimal safety factor (OSF) and develop a multi-criteria reliability-based design optimization based on the extended OSF for compliant mechanisms. In the case study, the proposed method is applied to a design of a thermal actuated compliant valve used for a micro water cooling system.
