Based on three-dimensional continuum topology optimization theory, aimed at maximizing compliance ratio, solid isotropic material with penalization model was used to establish the topology optimization model of a single-axis flexure hinge. With the help of OptiStruct, this paper designed a kind of single-axis flexure hinge with a new three-dimensional topological structure. Secondly, combining Castigliano's second theorem and the method of energy for the compliance of flexure hinge in theory, it deduced the compliance matrix of the new flexure hinge. 16 groups' analysis in theory and finite element simulation analysis showed the correctness of the theoretical formula because the relative error of analysis and FEA was within 6.35%. Finally, it compared the difference of compliance between the new flexure hinge and circular flexure hinge with the same cut profile. The results show that the new flexure hinge has much better performance in compliance. Compared with the circular flexure hinge, its compliance can be improved by 300%. Based on the three-dimensional continuum topology optimization method, this paper presented a new thought for the design of single-axis flexure hinge.
