Vibration Suppression by Variable-Stiffness Members

AIAA Journal, 1990
The active vibration suppression with this type of variable-stiffness member is shown to be always stable. A theoretical investigation on a single-degree-of-freedom system shows potential high efficiency for this type of variable-stiffness system due to its unique hysteretic ...

Towards a robust variable stiffness actuator

2013 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2013
Robots with Variable Stiffness Actuators (VSA) are intrinsically flexible in the joints. The built-in mechanical spring not only has the advantage of a higher peak performance, but also leads to a more robust robot. This paper presents and analyzes the threats to a VSA equipped robot that arise from external or internal origin. Influences of mechanical,

Variable Stiffness Structure for limb attachment

2011 IEEE International Conference on Rehabilitation Robotics, 2011
In robotic rehabilitation, the way of attaching the robotic device to the users' limb constitutes a crucial element of product quality, particularly for assuring good fitting, comfort, accuracy, usability, and safety. In this article, we present a new technological concept - 'Variable Stiffness Structure' - allowing for an improvement of these aspects ...

Stiffness control of variable stiffness joint using electromyography signals

2013 IEEE International Conference on Robotics and Automation, 2013
We have developed a multi-functional joint mechanism with variable joint stiffness and the ability to sense external forces. In this joint, silicone rubber cushions are employed to adjust the joint stiffness by controlling the pressure in the cushions.

Optimisation of Variable Stiffness Plates

Applied Mechanics and Materials, 2016
Variable angle tow (VAT) describes fibres in a composite lamina that have been steered curvilinearly. In so doing, substantially enlarged freedom for stiffness tailoring of composite laminates is enabled. VAT composite structures have been shown to have improved buckling and postbuckling load carrying capability when compared to straight fibre ...

Colonoscopy with the Variable Stiffness Colonoscope

Gastrointestinal Endoscopy, 2003
During colonoscopy, sharp angulations and fixation of the bowel increase the difficulty of the procedure. Excessive “looping” of the bowel implies that the force of scope insertion is transferred to the colon wall or to its mesenteric attachment instead of to the forward advancement of the leading tip of the colonoscope.
