“…The tensile flexibility coefficient C F and the rotational flexibility coefficient C M of the RCF and the CRF could be obtained from the literature (Bolzmacher et al, 2010;Ma et al, 2006;Xu and Li, 2011); then the compliance ratio λ could be obtained from Eqs. ( 23) and ( 24).…”

“…Structural compliance directly affects the overall performance of the compliant micro-displacement amplification mechanism. Many scholars studied structural compliance and the amplification performance of the compliant mechanism using different modeling methods Zhu et al, 2020;Liu, 2013;Bi et al, 2010;Lobontiu and Cullin, 2013;Lobontiu, 2014). These authors' research approaches always suggest the need to fix the structure geometry first, subsequently analyze the compliance, and finally optimize the design (Wang et al, 2020;Tan et al, 2019;Qi et al, 2018Qi et al, , 2019.…”

“…Li et al (2011) calculated the output displacement and the amplification gain of the bridge micro-displacement amplification compliant mechanism by the matrix method. Bolzmacher et al (2010) studied the multi-stage lever displacement amplification mechanism and simulated the amplification performance of the compliant mechanism by using finite element analysis. Ma et al (2006) simplified the calculation formula for the compliance and displacement of the bridge-type amplification mechanism, and the properties of the amplification gain for the bridge-type mechanism were also discussed based on the elastic beam theory.…”

Abstract. In order to improve the key performance of the compliant actuators, it is necessary to parametrically optimize the compliant actuators based on the compliance features of flexible hinges. A new structural parameter λ, the compliance ratio, which could reflect the sensitivity of the main form of the output displacement, was proposed and analyzed in detail. A compliant lever actuator was developed, and it was optimized by making use of the parameter λ. The optimization was also validated by finite element method (FEM) simulation and experiment. The simulation and experiment results both show that the magnification ratio of the compliant actuator could be enlarged effectively based on the compliance features of flexible hinges. Finally, an actual application of the linear positioning platform that was driven by the compliant lever actuator directly was carried out, and the experiment data also show that the platform with the optimized actuator has different degrees of optimization in terms of the key performance, including the resolution, the motion speed, and the working stroke. It is helpful to develop the compliant actuators and apply it into the precision engineering.

To achieve the requirement of flexure hinges for specific optical precision equipment, a new triangular bi-axial flexure hinge is proposed. The analysis model for the flexibility of the triangular bi-axial flexure hinges is derived. After that, the linear and nonlinear finite element methods are used to verify the analysis model. Then, the physical dimensions of the hinge are optimized using the multi-island genetic algorithm in conjunction with the finite element method, and the rotational stiffness and center drift are diminished. Static analysis and modal analysis of the hinge are conducted. A test system was built to gage the flexure hinge’s rotational stiffness. The results demonstrated that there was good agreement between the analytically calculated value, simulated calculated value, and experimental value. To summarize, the analysis model met the design requirements of the triangular bi-axial flexible hinge, and the multi-island genetic algorithm effectively optimized the physical dimensions of the hinge and enhanced its performance. The design process provides new ideas for the design of other forms of hinges.

“…Similar curved designs with thicker out-of-plane dimension for in-plane bending applications include planar rotarymotion bearings (Shusheng et al, 2010), the serial chain containing rigid members interspersed with straight-axis and one circular-axis flexible portions (Hsiao and Lin, 2001), and the hybrid bi-directional elastic-annulus flexure joint (Lee and Ziegert, 2007). Flexible robotic limbs for planar or spatial motion, comprised of circularaxis segments in serial flexible chains, have been analyzed and designed by several researchers including Lobontiu et al (2001b) and Callegari et al (2009) rigid-body model has been applied to design large-deformations curved beams of constant cross-section by Howell (2001) and Jagirda (2006), among others.…”

The new class of flexure hinges with circular longitudinal axis and midpoint radial symmetry is introduced. Using rotation and mirroring, the symmetric flexure hinge is obtained from one half flexure. The six planar-bending compliances of the full hinge are determined analytically for small deformations by combining only three compliances of the half flexure. To illustrate the general flexure hinge category, the novel circular-axis, right circularly corner-filleted design is introduced. Experimental and finite element results correlate well with the analytical model predictions. The new flexure hinge design is compared to the circular-axis, constant-thickness flexure and the straight-axis, right circularly corner-filleted hinge.
