Download or read book STUDIES OF SHIP MANEUVERING RESPONSE TO PROPELLER AND RUDDER ACTIONS written by and published by . This book was released on 1965 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: An attempt is made to extend ship-maneuvering analysis for application at low ship speeds. Captive-model experiments are made to investigate effects of non-equilibrium propeller speeds on rudder force and effective thrust. Other experiments are made to explore first-order effects of very large drift angles and pure yaw rotation on hull hydrodynamic reactions. The experimental results, together with previous rotating-arm data, are applied in motion equations, accounting for both extreme propeller actions and the occurrence of large drift angles and turning rates. Also included are propulsion and rudder time lags, and the influence of uniform water current on ship trajectory. The equations are programmed for computation, and ship response to a simple docking maneuver is predicted. The computation is repeated several times to examine sensitivity of ship motions and trajectory to variations of operating parameters, namely, maximum reverse propeller speed, engine response time, and water-current direction.

Download or read book Ship Maneuvering Including the Effects of Transient Motions written by Carl Alden Scragg and published by . This book was released on 1976 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the traditional approach to the problems of ship maneuvering, on uses a set of linearized equations of motion that excludes the possibility that the hydrodynamic forces and moments might be affected by the history of the motion. Using ideas introduced by Cummins, one can obtain another linearized set of the equations of motion which contains a 'memory function' as well as the added mass and damping coefficients. These stability coefficients have been evaluated by an impulse-response techniques, a method that is new to ship maneuvering problems and that appears to represent a substantial improvement over the traditional regular-oscillatory-motion tests. Results from both experimental methods are presented for comparison. To examine the effect of the memory function upon predictions of standard ship maneuvers, predictions of a few standard maneuvers have been calculated using both sets of the linearized equations of motion. The differences between the predicted motions were found to be small for all the cases we examined. (Author).

Download or read book Practical Ship Hydrodynamics written by Volker Bertram and published by Elsevier. This book was released on 2012 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical Ship Hydrodynamics provides a comprehensive overview of hydrodynamic experimental and numerical methods for ship resistance and propulsion, maneuvering, seakeeping and vibration. Beginning with an overview of problems and approaches, including the basics of modeling and full scale testing, expert author Volker Bertram introduces the marine applications of computational fluid dynamics and boundary element methods. Expanded and updated, this new edition includes: Otherwise disparate information on the factors affecting ship hydrodynamics, combined to provide one practical, go-to resource. Full coverage of new developments in computational methods and model testing techniques relating to marine design and development. New chapters on hydrodynamic aspects of ship vibrations and hydrodynamic options for fuel efficiency, and increased coverage of simple design estimates of hydrodynamic quantities such as resistance and wake fraction. With a strong focus on essential background for real-life modeling, this book is an ideal reference for practicing naval architects and graduate students.
