On synchrophasing control of vibration for a floating raft vibration isolation system
(2014-01-01)
A large-scale floating raft vibration isolation system installed on a flexible hull-like structure is described in this paper. Four vibration exciters, in which two counter rotating shafts with the same balanced masses are ...
A novel gastroretentive floating system for zidovudine, based on calcium-silicate beads
(Academic Journals, 2013)
The aim of the research effort entertained herein was to develop, evaluate and fully characterize a multiparticulate floating gastroretentive system for the modified release of zidovudine (AZT), an antiretroviral drug. AZT ...
On synchrophasing control of vibration and sound radiation for a floating raft vibration isolation system
(2014-01-01)
For the purpose of solving the problems of vibration transmission and sound radiations in ships, synchrophasing control technology was presented. The phases of multiple rotating or reciprocating machines installed on a ...

(Academic Journals, 2016)
Nonlinear identification of mooring lines in dynamic operation of floating structures
(Elsevier, 2004-12)
An adaptive algorithm for on-line estimation of physical coefficients of cables in viscous environment is presented. The procedure is useful for obtaining cable characteristics, which are needed in stability analysis and ...
Analysis of a Simplified Model of Rigid Structure Floating in a Viscous Fluid
(Springer New York LLC, 2019)
We study the interaction of surface water waves with a floating solid constraint to move only in the vertical direction. The first novelty we bring in is that we propose a new model for this interaction, taking into ...
On-line Identification and Convergence Analysis of Excitation -Force and Drag-Force Models for Moored Floating Structures
(Elsevier, 2005-12)
This work presents an approach to identify hydrodynamic models for incident, diffraction and viscous forces acting on a moored floating structure. An important aspect treated here is the analysis of the unknown initial ...
Vibration Control of a Floating Raft System by Synchrophasing of Electrical Machines: An Experimental Study
(2018-08-01)
This paper describes an experimental investigation into the vibration control of multiple electrical machines installed on a large-scale floating raft system. Vibration transmission to a flexible hull-like structure that ...
Full modeling of the mooring non-linearity in a two-dimensional floating structure
(Pergamon-Elsevier Science Ltd, 2006-01-05)
The dynamic behavior of a two-dimensional model of a small floating structure anchored by chains is analyzed. The structure is first modeled as a two-degrees-of-freedom oscillator with a strongly non-linear stiffness and ...
Combining active control and synchrophasing for vibration isolation of a floating raft system: An experimental demonstration
(2020-01-01)
Vibration isolation of a floating raft system typically found in a marine application is of concern in this paper. Housed on the raft are electrical motors each driving two counter rotating shafts with eccentric masses ...
