Yacht design (1985)
AuthorsHolland, K. J.show all
The problem being researched is that of how computers can help in the design process that is employed in designing a yacht hull. This is a problem that has been researched before but with different results to what have been achieved in this project. The main aims were not to provide a true computer aided design program, but a useful set of tools that can be used in the design process. The manual process for drawing up a set of curves to represent a hull is a tedious process that often suffers from loss of accuracy on the drawing board. After an initial set of lines has been drafter, the process of refinement begins until the shape is acceptable to the designer. The final stage of the design is to perform a simple analysis of the design, usually in the form of a displacement approximation and a curve of area to estimate the centre of displacement from. Any designer doing a thorough job will make detailed analysis of the weight that goes into a boat to find the centre of mass of the boat. This is followed by an accurate as possible estimate of the centre of displacement of the boat and an effort to balance the centres of mass and displacement. If this not done the boat will not float on its designed water line. It is very had for the computer to help in the estimate of the mass that goes into the boat without a great deal more information than will be considered in this project. Where the computer can help is in the process of finding the displacement and centre of displacement. This is not a trivial process to perform by hand, as well as being very inaccurate in most cases. Using a suitable numerical method, the computer can make a more accurate estimate of these parameters.
