Reconfigurable Soft Flexure Hinges via Pinched Tubes
2020 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2020Tuning the stiffness of soft robots is essential in order to extend usability and control the maneuverability of soft robots. In this paper, we propose a novel mechanism that can reconfigure the stiffness of tubular structures, using pinching to induce highly directional changes in stiffness.

Generalized model and performance analysis of elliptical-fillet cross-sectional flexure hinges
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2023This work presents the design and analytical model of a novel flexure hinge with variable elliptical-fillet cross-section, which can be considered as an extension of existing results on rectangular and/or circular cross-sectional flexure hinges.

A 2-D Fiber Bragg Grating Acceleration Sensor Based on Circular Flexure Hinges Structure
IEEE Transactions on Instrumentation and Measurement, 2023This work proposes and experimentally validates a 2-D low- and medium-frequency fiber Bragg grating (FBG) acceleration sensor. The investigation of the vibration sensor uses a symmetrical circular flexure hinge structure with similar sensitivity in both ...

Design and analysis of the power-trigonometric function-shaped flexure hinges.
Review of Scientific Instruments, 2023In this paper, a generalized flexure hinge model, that is, power-trigonometric function-shaped flexure hinges (PTFHs), is proposed. The power function and trigonometric function in the curve function are changed, which obtains different notch types of ...

Review of Scientific Instruments, 2013
This paper designs and analyzes the hybrid flexure hinge composed of half a hyperbolic flexure hinge and half a corner-filleted flexure hinge. As it is transversely asymmetric, it has different performance when the fixed and free ends switch.

Proceedings. 2005 IEEE Networking, Sensing and Control, 2005., 2005
The paper introduces two hybrid flexure hinges: right-circular corner-filleted (RCCF) and right-circular elliptical (RCE) hinges. Closed-form compliance equations are formulated. Checked by the finite element analysis, the theoretical formulation data are within 8 percent error margins. The results indicate that the RCCF flexures have the best rotation-

Review of Scientific Instruments, 2015
Flexure-based mechanism like compliant actuation system embeds complex dynamics that will reduce the control bandwidth and limits their dynamic positioning precision. This paper presents a theoretical model of a leaf flexure hinge with damping layers using strain energy method and Kelvin damping model.

Review of Scientific Instruments, 1997
This paper presents closed form equations based on a modification of those originally derived by Paros and Weisbord in 1965, for the mechanical compliance of a simple monolithic flexure hinge of elliptic cross section, the geometry of which is determined by the ratio ε of the major and minor axes. It is shown that these equations converge at ε=1 to the
