“Dynamics of a Rigid Ship - with applications”: a freely available book on nonlinear ship dynamics by Prof. Jerzy Matusiak - Aalto University (Finland)
The 3rd edition of “Dynamics of a Rigid Ship - with applications”, written by Prof. Jerzy Matusiak (Aalto University - Finland), is freely available for download from:
http://urn.fi/URN:ISBN:978-952-64-0399-1
The book is primarily meant as textbook of the course “Ship Dynamics” provided for the students of Maritime Engineering of Aalto University.
This textbook is a result of the work started in 1996 when the author joined a very interesting, newly formed Specialist Committee working on Ship Stability within the International Towing Tank Conference (ITTC). Thanks to this group of international enthusiastic scholars in the field, it became clear for the author that both the research and the rules’ development in the field of ship stability will proceed in the direction of including ship dynamics. Moreover, this development will require sophisticated mathematical models of ship dynamics, to be verified and thoroughly validated, based on the first principles and taking realistically into account the environmental, often very hostile, conditions.
The approach to ship dynamics presented in the book makes it possible to deal with the seemingly different problems such as ship maneouvring, sea-keeping and dynamic stability using the same unified mathematical model. Motion dynamics of a ship regarded as a rigid body in a general motion with six-degree-of-freedom is considered. The relation of non-linearities of the applied sub-models to the physical phenomena associated with the ship behaviour is discussed. Surface wave theory is presented. Non-linearities associated with surface waves are discussed. Realization of the unified mathematical model in a form of simulation tool, called LaiDyn, is discussed and examples of its applications are shown. Mathematical model for assessing internal hull girder loads is presented briefly. An un-symmetry of internal loads, visible as different maximum values of sagging and hogging, is presented and the origins of it are discussed.
Apart corrections there are several additions included in the 3rd edition. Mainly they concern applications of the LaiDyn method presented the earlier editions. Recent developments of the method are discussed as well. These concern mainly ship manoeuvring in irregular waves.
The 3rd edition of the book comprises two parts.
In the first part, theoretical background and mathematical models making up an entity capable to describe ship behavior in sea waves are presented. Numerical implementation of the models, in a form of LaiDyn computer program, is also briefly discussed. The discussion on the effect of hull flexibility on the girder internal loads and response to wave loading is added.
The second part discusses validation of the method and presents particular applications of the method. These applications were presented in publications co-authored by Prof. Matusiak colleagues (Maria Acanfora, Patrik Rautaheimo, Tomasz Hinz and Jakub Montewka) and himself.
It is in the hope of the author that this book will be of interest for the researchers working in the field of Ship Dynamics and particularly for the post-graduate students.
