This book was released on 1977 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical model is developed for the prediction of ship lateral motions in oblique seas. The asymptotic behavior of this model in waves that are long relative to ship beam is examined, with particular emphasis on the classical problem of rolling in beam seas. The theoretical prediction of roll damping is discussed, and the importance of including dynamic lift on appendages is emphasized. Fairly extensive comparisons of predicted and measured roll response are made, with good agreement at all headings considered. (Author).

Research and Development Branch and published by Research and Development Branch, Department of National Defence. This book was released on 1976 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: To provide further capability for prediction and analysis of hydrofoil hullborne seakeeping, a mathematical model and computer program have been developed to predict roll, sway and yaw motions of hullborne hydrofoil ships in beam seas. Predictions agree well with towing tank data for a 1:20-scale model of the PHM hydrofoil craft. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Descriptions of two digital computer programs which calculate the motion of a mono-hull ship or a twin-hull ship are given. The ship is assumed to be advancing at constant speed with arbitrary heading in regular waves. The heave and pitch motion equations are solved in the program MOT35; the sway, roll and yaw motion equations are solved in the program MOT246. Computer input and output and program usage are described. Listings of the program as well as sample input and output are given. (Author).

Download or read book Contemporary Ideas on Ship Stability written by Vadim L. Belenky and published by Springer. This book was released on 2019-01-01 with total page 931 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a selection of research papers presented at the 11th and 12th International Ship Stability Workshops (Wageningen, 2010 and Washington DC, 2011) and the 11th International Conference on Stability of Ships and Ocean Vehicles (Athens, 2012). The book is directed toward the ship stability community and presents innovative ideas concerning the understanding of the physical nature of stability failures and methodologies for assessing ship stability. Particular interest of the readership is expected in relation with appearance of new and unconventional types of ships; assessment of stability of these ships cannot rely on the existing experience and has to be based on the first principles. As the complexity of the physical processes responsible for stability failure have increasingly made time-domain numerical simulation the main tool for stability assessment, particular emphasis is made on the development an application of such tools. The included papers have been selected by the editorial committee and have gone through an additional review process, with at least two reviewers allocated for each. Many of the papers have been significantly updated or expanded from their original version, in order to best reflect the state of knowledge concerning stability at the time of the book’s publication. The book consist of four parts: Mathematical Model of Ship Motions in Waves, Dynamics of Large Motions, Experimental Research and Requirements, Regulations and Operations.

Download or read book Ship Motion Control written by Tristan Perez and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: engineers into a single volume whilst concentrating on two important research control design problems: autopilots with rudder-roll stabilization and fin and combined rudder-fin stabilization. He has been guided by some of the leading marine control academics, in particular Mogens Blanke and Thor Fossen; indeed Chapters 3 and 4 on kinematics and kinetics of ship motion are jointly authored with Professor Fossen. There are some 240 cited references – an invaluable resource for interested readers. The volume is likely to appeal to a wide range of readers who will each be able to extract something different from the various parts of the monograph. Part I has some four chapters on the modelling fundamentals including kinematics, dynamics and actuators. Part II is a very useful survey of the ship roll stabilization problem and how ship roll performance is measured and assessed. This clearly motivates the human necessity for roll-reduction and roll stabilization. Parts III and IV move on to the control systems aspects of the various stabilization designs. Valuable material here includes a study of system performance limitations as caused by the presence of non-minimum phase characteristics and actuator saturation. Chapter 10 has an interesting historical review of these marine control problems stretching back some thirty-years into the 1970s.

Download or read book On the Stability of Ship Motion in Regular Oblique Waves written by Mahmoud R. Haddara and published by . This book was released on 1970 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nonlinear equations of motion of a ship sailing in regular oblique waves are formulated and an analytical method is developed to obtain an approximate solution for them. The stability of the steady-state solution is investigated by examining the behavior of the solution of the equations of the first variation of the equations of motion. The study shows that the existence of unstable motion is predicted for certain cases if we take account of nonlinearities in the equations of motion. This instability is very sensitive to variations in the nonlinear damping coefficient in roll. (Author).

Book excerpt: "Vive la Revolution!" was the theme of the Twenty-Third Symposium on Naval Hydrodynamics held in Val de Reuil, France, from September 17-22, 2000 as more than 140 experts in ship design, construction, and operation came together to exchange naval research developments. The forum encouraged both formal and informal discussion of presented papers, and the occasion provides an opportunity for direct communication between international peers. This book includes sixty-three papers presented at the symposium which was organized jointly by the Office of Naval Research, the National Research Council (Naval Studies Board), and the Bassin d'Essais des Carènes. This book includes the ten topical areas discussed at the symposium: wave-induced motions and loads, hydrodynamics in ship design, propulsor hydrodynamics and hydroacoustics, CFD validation, viscous ship hydrodynamics, cavitation and bubbly flow, wave hydrodynamics, wake dynamics, shallow water hydrodynamics, and fluid dynamics in the naval context.
Download or read book Prediction of Ship Motions in Regular and Irregular Head Waves written by E. N. Hubble and published by . This book was released on 1975 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current techniques for the prediction of ship motions in long-crested head waves are discussed. Addition of a speed term to the theoretical pitch damping coeffieient is correlated with experimental data. The relationship between absolute and relative motion along the ship length is discussed. Practical limits are established for integrating the spectral density functions for irregular-sea responses. Recommendations are made for updating computer program YF17, computing irregular wave responses with either idealized or real sea spectra such as the Station INDIA data.
