Flexible hinges have some characteristics, such as small volume, without rubs, ceaseless, good rigidity and high sensitivity. As the traditional hinge been replaced with the flexible hinge, the parallel mechanism just right have the above advantages, and suitable be used for micro-motion robot. Flexible hinges are widely used in micro robotic, and the(More)
The purpose of this paper was to investigate the reason why the interface delaminations occurred in the QFP structure. The stress concentration was the key factor responsible for the microcrack occurrence. In order to figure out which factors affect the stress distribution, the material's attributes and the structure's dimension were considered. The finite(More)
—In order to investigate the flow field and heat transfer in a channel with one square rib on upper wall and two on lower wall, standard k ε − turbulence model and enhanced wall function was employed. The influence of the conductivity ratio s f k k (solid/fluid) on the heat transfer around the rib surface was explored. The results show that the maximum(More)
