Analysis of the Rigidity of an Elliptical Flexible Hinge with Different Geometrical Parameters

Flexible hinges are widely used in micro robotic. Its rigidity directly influences an organization´s terminal localization. Its actual structure geometry size cannot satisfy the theoretical analysis completely in a theoretical supposition condition. In this paper, we analyzed the rotation rigidity of a elliptical flexible hinge in different parameters using finite element software ANSYS. The errors are discovered and compared with theoretical result. Though the graph of the flexible hinge parameters and its performance, an analysis of changes of 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.
