...Zhongyuan Ping; Tianci Zhang; Chi Zhang; Jianbin Liu; Siyang Zuo This paper presents a novel miniature contact-aided compliant mechanism (CCM) that includes flexure hinges and contact-aided structures. This continuum mechanism comprises a nickel–titanium alloy (Nitinol) tube with CCM cut via laser...

... flexure hinge design mathematical model compliance stiffness out-of-plane small deformations large displacements Flexible (compliant) mechanisms for out-of-plane, z -axis (piston) motion have been developed to cover a wide array of applications at both the macro- and micro/nanoscales...

... 02 2014 23 07 2014 The paper introduces a new category of planar flexure hinges that are formed by serially connecting variable cross-sectional segments of straight longitudinal axes with segments of circular longitudinal axes. The small-displacement compliance analytical model...

.... As a result, the linearity of motion and stability are improved. With circular flexure hinges being treated as revolute joints, the forward kinematics and inverse kinematics of the 3-DOF manipulator are analytically derived. Computational analyses are performed to validate the established kinematics models...

... since almost all flexure hinges, through their defining geometry, present stress concentrations at the regions where they connect to the rigid links (see the configuration of Fig. 2 ). Stresses can however be evaluated, provided that stress concentration coefficients are available for a given flexure...
