The Degree of Translational-Rotational Coupling of a Spatial Stiffness

Dynamic Systems and Control, 1999
Abstract Previously, we have shown that, to realize an arbitrary spatial stiffness matrix, spring components that couple the translational and rotational behavior along/about an axis are required. We showed that, 3 such coupled components and 3 uncoupled components are sufficient to realize any full-rank spatial stiffness matrix and that

The vsaUT-II: A novel rotational variable stiffness actuator

2012 IEEE International Conference on Robotics and Automation, 2012
In this paper, the vsaUT-II, a novel rotational variable stiffness actuator, is presented. As the other designs in this class of actuation systems, the vsaUT-II is characterized by the property that the output stiffness can be changed independently of the output position. It consists of two internal elastic elements and two internal actuated degrees of

Measurement for the identification of static and quasi-static rotational stiffness

Precision Engineering, 2021
Machine tool calibration can be employed to optimise tool path trajectories through on- and off-line compensation of anticipated deflections, which result from a process plan, and to assess the machine tools capability to comply with the geometric ...
