An Experimental Test Bench for Cable-Driven Transmission

An Elastic Cable Model for Cable-Driven Parallel Robots Including Hysteresis Effects

Experimental results indicate that time invariant linear elastic models for cable-driven parallel robots show a significant error in the force prediction during operation. This paper proposes the use of an extended model for polymer cables which allows to regard the hysteresis effects depending on the excitation amplitude, frequency, and initial tension level. The experimental design as well as...

Automatic Test Bench Generation

In current design practice synthesis tools play a key role, letting designers to concentrate on the specification of the system being designed by carrying out repetitive tasks such as architecture synthesis and technology mapping. However, in the new design flow, validation still remains a challenge: while new technologies based on formal verification are only marginally accepted for large desi...

Four-cable-driven parallel robot

This paper presents design and kinematic analysis for a cable-driven parallel robotic (CDPR) manipulator with four cables, The CDPR manipulator produces a planar motion including two translational and one rotational degrees of freedom. To move the end-effector of CDPR, its kinematic structure is analyzed and the inverse kinematics is formulated in the closed-form solution. The experimental test...

Design and Analysis of a Cable-Driven Test Apparatus for Flapping-Flight Research

Pure moment testing for spinal biomechanics applications: Fixed versus sliding ring cable-driven test designs.

In vitro multi-axial bending testing using pure moment loading conditions has become the standard in evaluating the effects of different types of surgical intervention on spinal kinematics. Simple, cable-driven experimental set-ups have been widely adopted because they require little infrastructure. Traditionally, "fixed ring" cable-driven experimental designs have been used; however, there hav...
