Abstract

The degree of freedom (DOF) is a significant index to reflect the moving capability of flexure mechanisms. Since the complexity and deficiency for analyzing the DOF of flexure mechanisms, two methods for analyzing the DOF of flexure mechanisms are presented. First one is a visualized method to analyze the DOF through mapping, based on the former research on graphic method, this method is simple and straight to be understood; the other method is based on the comparison of the normalized eigen-compliances of compliance matrix to analyze the DOF of flexure mechanisms. After the detailed analyzing on parallelogram flexure module, cartwheel flexure module, and the combination of these two modules, the derived two methods are certified their validity and practicability.

Key words： screw theory; graphic method; degree of freedom; eigen analysis
