Vibration Suppression Control of a Space Robot with Flexible Appendages Based on Simple Dynamic Model

, 2013
This paper discusses a vibration suppression control method for a space robot with a rigid manipulator and flexible appendage. A suitable dynamic model that considers the coupling between the manipulator and flexible appendage was developed for the ...

Newly Constructed Subway on Over-Track Bridge Safety and Vibration Reduction Measure

Advances in Civil Engineering
Primarily generated at the interface between the wheel and the rail, railroad vibrations then propagate through the supporting soil. If these vibrations reach nearby bridges and buildings, they amplify the vibration nuisance and cause ground noise, which

F.E.V.E. tunnel railway. Prediction of ground-borne noise and vibration

, 2005
The railway line Amezola-Basurto in Bilbao is planned to be converted from a surface line to a tunnel line. The train traffic on the line is mainly suburban trains operated by FEVE and a few freight trains. The new tunnel will be a concrete tunnel of the

Computational modelling of acoustic scattering of a sound source in the vicinity of the ground [PDF]

, 2009
The paper presents a computational model for acoustic scattering of a near-the- ground sound source around a body moving in a uniform flow. Using the method of images and the concept of reflection coefficient, the half space Green's function in a ...
