摘要

This paper proposes a novel single-axis Multicavity Flexure Hinge (MCFH) consisting of the symmetric cycloidal notches and the multiple cavities. This flexure hinge is firstly designed based on the three-dimensional continuum topology optimization (3-DCTO). And then post-processing is used to obtain the final configuration of the hinge. In order to study the effect of the stiffness performance on different geometric parameters of the hinge, the dimensionless stiffness empirical equations are derived based on finite element analysis (FEA). Subsequently, the new flexure hinge is compared with various types of hinges on the performance. The results show that the presented flexure hinge has greater compliance in the working direction and the results also confirm the 3-DCTO method can provide a new idea for the design of flexure hinges in the future.
