Unlike the 1-DOF freedom PRBM used in the existing literature, the PRBM proposed has 3-DOF (degrees of freedom). Using the 3-DOF PRBM of flexure hinges, planar flexure-hinge mechanisms can be represented as rigid multibody systems whose adjacent rigid bodies are connected by 3-DOF joints. After applying this modeling procedure, the principle of virtual work yields a matrix relation for the determination of the quasi-static responses of a flexure mechanism due to external loads. The validity and accuracy of the approach for quasi-static analysis of planar flexure-hinge mechanisms based on the 3-DOF PRBM are examined using the examples of two types of compliant mechanisms: RRR and 3-RRR compliant micro-motion stages.restrictedAccessarticle10.1016/j.mechmachtheory.2018.02.0112-s2.0-85043346143
