Abstract

This paper studies the performance of symmetric single-axis flexure hinges, including their capacity of rotation, precision of rotation and stress level. In order to expand the motion stroke of the flexure hinge and reduce its parasitic motions, a multi-objective optimization model is established. For six types of flexure hinges including circular, elliptical, rectangular, parabolic, hyperbolic and corner-filleted, a Computer-Aided optimal Design and Analysis Platform (CADAP) based on Visual C++ is developed. Taking parabolic flexure hinge as an example, the results of finite element analysis (FEA) verify the correctness of the theoretical analysis and CADAP.
