In the study, based on the material mechanics principles, it sets up the flexible hinge math model. In the model, the flexible hinge rigidity formula derivation is made by hinge?s micro-unit mechanics analysis and calculation. Study the influence of flexible hinge radius R, minimum thickness t, width b on the flexible hinge rigidity k. Design a flexible hinge supported twin-parallel 4-bar guide mechanism. The mechanism?s key parameters: Rigidity K, max stress σmax, max output displacement Δymax and natural frequency f and their relations are revealed through mechanics analysis method to optimize mechanism design.
