Research on a Novel Flexure Hinge

摘要：

A novel single axis flexure hinge named hyperbolic flexure hinge is introduced as new designs in two-dimensional monolithic mechanisms. Based on the Castiglianos second theorem, Closed-form equations are formulated for compliances to characterize both the active rotation and all other parasitic motions. Precision of rotation and the stress levels are also evaluated in terms of compliances. A unitary compliance-based analysis is performed by means of two-dimensional geometric parameters by which the performance of flexure hinge can be evaluated in terms of their desired flexibility, capacity of preserving the centre of rotation position and stress levels. Checked against finite element analysis, the model predictions are within8％ error margins. So some theoretic foundation for flexure hinges design is provided.
