Based On The Arx Hull Solid Modeling And Applied Research

Nowadays, the technology of CAD is deeply applied in more and more fields. It makes a big revolution in nearly all the design realm. The application of three-dimensional design is the result of technology development. As the base of three-dimensional design, geometry modeling technology will restrict the degree of three-dimensional design's application. Solid modeling, the most perfect in geometry modeling, is studied in this article under practicality's direction. As examples, the solid ship and solid holds are designed. The corresponding software is also developed. This pushes the design to the right direction of three-dimensional design. The chief achievement of this article is listed as follows:i) With the help of the ARX tools, a method of constructing the ship's solid modeling is presented based on the ship's surface modeling. This model is simple and reliable. The following design of real ship proves the validity of this method.ii)The studying on tanks' solid modeling is developed with ARX tools. All the holds are classified and expressed with different ways. A example of real ship attests the utility of this method. This benefits the ship holds subdivision design in three-dimensional way.iii) The stability calculation based on solid modeling is studied. The idea of calculation with three-dimension is bringing forward. It can nearly apply to all kinds of stability calculation. A correction method for effect on stability of free surface is putting forward. This method is based on reality and three-dimensional technique. The programs of stability curve calculation, free surface correction and holds capacity volume calculation are developed with AutoCAD ARX.
