Its tigidity directly influences an organization’s terminal localization. Its actual structure geometry size cannot satisfy the theoretical analysis pletely in a theoretical supposition condition. In this paper. We analayzed the rotation rigidity of a ellliptical flexible hinge in different parameters using finite element software ANSYS. The errors are discovered and pared with theoretical result. Though the graph of the flexible hinge parameters on the performance of a elliptical flexible hinge was carried out. The key manufacture parameters that affect the performance of an elliptical flexible hinge the most and rules of design are given, which can provide directions of design precision for the flexible hinge.

With micoputer electrical system series (MEMS) technical rapidly expanding, flexible hinge are widely applied in the displacement which requests small angular and highprecision rotation, such as gyroscopes,accelerometers, percision instruments and so on. It has broad application prospects in the micron level domain. The mon flexible hinge is in two kinds:beamshape flexible hinge and arcshaped flexible hinge. The beamshaped flexible hinge has a big slewing area, but the movement precision is bad. The arcshaped flexible hinge’s movement percision is bad. The arcshaped flexible hinge is relatively small. In order to take into account the movement ptecision and scope, the following several rotation flexible hinges have been generated: parabolic flexure hinge, an elliptical flexure hinge and a hyperbolashaped hinge, etc. The properties of flexible hinges are rigidity precision and stress characteristic etc. the rigidity performance reflects the stress ability and also manifests movement to a viceflexible degree. In 1965, Parosetal announced his design development of the circular flexible hinge for the first time, and gave the rigidity used the similar method to obtain an elliptic flexible hinge mechanics expression.
