A fully compliant five-link mechanism of two-DOF was analyzed with both pseudo-rigid-body and imitate-compliant-body models. The pseudo-rigid-body and the imitate-compliant-body model of the fully compliant five-link mechanism were also established and the equation of relationship for load and displacement was presented. A symmetry fully compliant five-link micro-mechanism was designed. By using the geometric relationships of the rigid five-link mechanism and the iterative program, the results of deformation analysis in imitate-compliant-body model method for this micro-mechanism were given. At the same time, the simulation analysis in the FEM method for the micro-mechanism was also given. Compared the results with computer and FEA, the validity of the imitate-compliant-body model was proved to be effective.
