On the Normal Modes of Nonlinear Coupled Ship Motions and Their Stability
Author: W. D. Kinney
Publisher:
ISBN:
Category : Ships
Languages : en
Pages : 68
Book Description
The concept of normal oscillations of a nonlinear conservative system is introduced and applied to the ship motion problem. In addition the stability of these normal modes is investigated and found to depend in general on the same parameters given in previous investigations. Since the normal oscillations represent a combined motion in the degrees of freedom concerned, an unstable mode does not necessarily imply unbounded motion in any one of the degrees of freedom. Since the system is assumed to be conservative, all displacements are necessarily finite. A knowledge of those straight normal modes which are stable is important since it is reasonable to conclude that the motion of ships in calm water will take place near those normal modes. In the absence of damping, the system is conservative, and hence the total energy of the system is a constant. This implies that all displacements and velocities must be finite. Because damping is always present, the system must ultimately reach a stable equilibrium position since energy is constantly dissipated from the system. (Author).

Contemporary Ideas on Ship Stability
Author: D. Vassalos
Publisher: Elsevier
ISBN: 008054701X
Category : Technology & Engineering
Languages : en
Pages : 609
Book Description
Widely publicised disasters serve as a reminder to the maritime profession of the eminent need for enhancing safety cost-effectively and as a strong indicator of the existing gaps in the stability safety of ships and ocean vehicles. The problem of ship stability is so complex that practically meaningful solutions are feasible only through close international collaboration and concerted efforts by the maritime community, deriving from sound scientific approaches. Responding to this and building on an established track record of co-operative research between UK and Japan, a Collaborative Research Project (CRP) was launched in 1995.This volume includes selected material from the first four workshops: 1st in University of Strathclyde, July 1995 organized by Professor Vassalos; 2nd in Osaka Japan, Osaka University, November 1996 organized by Professor Masami Hamamoto; 3rd in Crete Greece, Ship Design Laboratory of the National Technical University of Athens (NTUA-SDL), October 1997 organized by Professor Apostolos Papanikolaou; and 4th in Newfoundland Canada, Institute for Marine Dynamics, September 1998 organized by David Molyneux. It contains 46 papers that represent all currently available expertise on ship stability, spanning 17 countries from around the world. The framework adopted for grouping the papers aims to cover broad areas of ship stability in a way that it provides a template for future volumes.

Structural Dynamic Systems Computational Techniques and Optimization
Author: Cornelius T. Leondes
Publisher: CRC Press
ISBN: 9789056996581
Category : Technology & Engineering
Languages : en
Pages : 284
Book Description
There are various techniques to optimize either structural parameters, or structural controllers, but there are not many techniques that can simultaneously optimize the structural parameters and controller. The advantage of integrating the structural and controller optimization problems is that structure and controller interaction is taken into account in the design process and a more efficient overall design (lower control force/lighter weight) can be achieved, and also multidisciplinary design optimization can be performed. The down side is that the combined optimization problem is more difficult to formulate and solve, and computations are increased. This volume is a comprehensive treatment of dynamic analysis and control techniques in structural dynamic systems and the wide variety of issues and techniques that fall within this broad area, including the interactions between structural control systems and structural system parameters.

Nonlinear Dynamics of Piecewise Constant Systems and Implementation of Piecewise Constant Arguments
Author: Liming Dai
Publisher: World Scientific
ISBN: 9812818510
Category : Mathematics
Languages : en
Pages : 345
Book Description
Piecewise constant systems exist in widely expanded areas such as engineering, physics, and mathematics. Extraordinary and complex characteristics of piecewise constant systems have been reported in recent years. This book provides the methodologies for analyzing and assessing nonlinear piecewise constant systems on a theoretically and practically sound basis. Recently developed approaches for theoretically analyzing and numerically solving the nonlinear piecewise constant dynamic systems are reviewed. A new greatest integer argument with a piecewise constant function is utilized for nonlinear dynamic analyses and for establishing a novel criterion in diagnosing irregular and chaotic solutions from the regular solutions of a nonlinear dynamic system. The newly established piecewise constantization methodology and its implementation in analytically solving for nonlinear dynamic problems are also presented.
