Mechanics Analysis for Flexible Hinge Supported Fast Micro-feeding Mechanism

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 sigma sub( max), max output displacement Delta y sub( max) and natural frequency f and their relations are revealed through mechanics analysis method to optimize mechanism design.
