摘要	As common flexures in a parallel mechanism usually are machined in different directions, and it is difficult to integrate with a monolithie configuration, this paper proposes a thinned right-circular flexure hinge with three degrees of freedom. The flexure hinge can be fabricated merely along one direction, and is benefit for the spherical hinge applied in positioning mechanism with monolithic configuration. Based on Castigliano's displacement theorem, the compliance formulas of the thinned right-circular flexure hinge were derived. Finite element analysis was adopted to verify the compliance formulas and analyze the effect of the structure parameters on the compliance of the flexure hinge. Two cases on the compliance design for the application of the flexure hinge were discussed. The results show that the maximum variance between the theoretically calculated compliance value and the finite element analysis compliance value is within 20%. The parameters with the greatest impact on the compliance of the flexure hinge are the thickness b, the minimum notch spacing t, and the fillet radius r, successively. The above conclusions provide principles for the design and application of the thinned right-circular flexure hinge with three degrees of freedom. 2015, Chinese Academy of Sciences.
