Pseudo-rigid-body model of a six-bar full-compliant mechanism

A six-bar full-compliant mechanism was designed, and its pseudo-rigid-body model was established, which shows that it is composed of two compliant slide mechanisms. Deformation analysis of the full-compliant mechanism was performed according to the pseudo-rigid-body model, and a theoretical formula of force and displacement was deduced for the pseudo-rigid-body model. An example was presented to embody the full-compliant mechanism, and its relationship of force and displacement was numerically analyzed using ANSYS software. Meantime, a physical model of this example was manufactured for experimental measurement. By comparing the results of theoretical calculation, simulation analysis and actual measurement it can be concluded that the results of the three methods are basically the same, indicating that the theoretical derivation and analysis of the formula is correct, the simulation analysis is precise, and the design of the example is feasible to achieve the design goal.
