Structural Optimization of Ship Structures

Understands the foundations of structural technology in ship's hull. Understands the statistical analysis of loads, the background of the calculation methods for the response of hull girder. Understands the failure modes of hull girder and their modelling. Can apply the learned knowledge and methods in the dimensioning of the main structural members and choice of materials. The foundations of structural technology in ship's hull.

Authors: Javid Iqbal, Zhu Shifan. The development in the construction of unconventional ships and the implementation of lightweight materials have shown a large impulse towards finite element FE method, making it a general tool for ship design. This paper briefly presents the modeling and analysis techniques of ship structures using FE method for complex boundary conditions which are difficult to analyze by existing Ship Classification Societies rules. During operation, all ships experience complex loading conditions. These loads are general categories into thermal loads, linear static, dynamic and non-linear loads.

Caldwell Newcastle , M. Ochi Florida , and P. Juncher Jensen Tech. This early and sustained support was of immense help. The growing demand for more efficient marine transportation has already produced significant changes in ship sizes, types, and production methods, For example, since many new ship types have appeared, such as Ing carriers, multihull vessels, barge carriers, rovto vessels, surface effect ships, and hydrofoils. This ap- proach saves time in the design office and, since the ship must obtain the approval of a classification soci- ty, it also saves time in the approval process. In the ocean environment, an elementary form of this approach is already used for the design of off- shore structures, partly because there is little or no previous experience on which to rely, and partly be- cause of the high economic stakes involved.

For a structure as large and as complex as a ship there are three levels of structural design, the second and most central of which is the subject of this book. Concept design deals with the topology or overall ge ometry of the structure; preliminary design establishes the scantlings structural dimensions of all principal structural members; and detail design is concerned with local aspects such as joints, openings, and rein forcements. Overall structural geometry is generally determined by overall design requirements rather than by structural requirements, while detail design is largely guided and constrained by fabrication methods and requirements. Also, since local structural details are numerous and basically similar among various structures they lend themselves to standardization and to design from handbooks and structural codes. Thus, it is in preliminary design where the structural designer has the largest number of signifi cant decisions and options, and the greatest scope for optimizing the structure so that it best fulfi lls the objectives and satis fi es all of the various constraints and requirements. Rationally-based design is design from fi rst principles using the tools of modern engineering science: computers and the methods of structural analysis and optimization which computers have made possible.

The present paper presents a historical review associated with the research works on hull girder strength of ship and ship-shaped structures. Then, a new program is developed to determine the ultimate vertical bending moment of hull girder by applying direct method, stress distribution method, and progressive collapse analysis method.

 Не несет ответственности? - Глаза Стратмора расширились от изумления.  - Некто шантажирует АНБ и через несколько дней умирает - и мы не несем ответственности. Готов поспорить на любую сумму, что у партнера Танкадо будет иное мнение.

Его уже выставили сегодня из больницы, и он не хотел, чтобы это случилось еще. - Nimm deinen FuB weg! - прорычал немец.  - Уберите ногу. Взгляд Беккера упал на пухлые пальцы мужчины. Никакого кольца. Я так близок к цели, - подумал. - Ein Ring! - повторил Беккер, но дверь закрылась перед его носом.

 Ты мне только что приснился. Приходи поиграть. - На улице еще темно, - засмеялся. - А-ах, - сладко потянулась.  - Тем более приходи. Мы успеем выспаться перед поездкой на север. Дэвид грустно вздохнул: - Потому-то я и звоню.

 Он целый год хвастался, что разрабатывает алгоритм, непробиваемый для грубой силы. - Н-но… - Сьюзан запнулась, но тут же продолжила: - Я была уверена, что он блефует.
