In recent years, compliant mechanisms have been paid to attention as new mechanisms to replace traditional rigid link mechanisms. Compliant mechanisms achieve a specified motion by deforming the structure elastically instead of relying on joint movements. Compared to traditional mechanisms, compliant mechanisms have several merits due to their monolithic structure without joints. Thus, the use of compliant mechanisms in mechanical products, medical instruments and MEMS can be expected to increase. For such promising compliant mechanisms, although many design methods have been developed, their reliability is not sufficiently considered. Since compliant mechanisms are quite different from traditional mechanisms, it is difficult to configure safety factor empirically. Thus, in this research, optimal safety factor, one of reliability-based design optimization (RBDO), is introduced into compliant mechanism design. In compliant mechanism design, there are two important criteria: output displacement and stress, but traditional OSF considers only single reliability. Thus, existing OSF is extended to allow for considering multiple reliabilities. 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.
This 9th bi-annual conference serves as a Nordic complement to the large European and American conferences within the field of Engineering Design and Product Development. The conference topic is design in a wide context: Integrated Product Development, Engineering Design, Industrial Design and Conceptualisation. Suggested topics for paper submission are: - Product Development - Research approaches and topics - Design education and teaching Researchers, practitioners and students are invited...
Enhancing a Nordic approach to product development in industry, education and research...
