Research Of The High-efficiency Computer-aided Modeling Approaches Of The Superstructure Of Deep V Fishing Yacht Based On The SINOVATION Software

The continuously nationally economical boom realizes the dramatic development in the industry of yacht.However,the trend of prosperity in yacht industry encounters the defects in the technology of yacht design.The solution about the aspects of economy and efficiency has been the common target of the whole yacht industry.Experts focuses on the domain of body design of yacht for a period of time,and series of researching achievement appears in the academic and industrial sphere.But in the turf of studying of superstructure of yacht computer-aided modeling of high-efficiency still stays in the initial process.In perspective of design aesthetics of yacht,this thesis takes yacht modeling theory into deep researching.Through interviews with serial yacht-manufactures,and comparing abundant blue prints of V fishing yacht with their counterparts,this thesis picks up the characteristics of curves and surfaces of V fishing yacht and suggest to categorize the curves in superstructure of fishing boat into half circular-type,elliptic-type and free-curve-type,then with quadratic curves of NURBS this thesis describes the the free-curve-surfaces in the superstructure of fishing boat.By analyzing the characteristics of the superstructure of fishing boat,this thesis comes up with plane-depending methodology of modeling,and figures out the key points of quadratic curves of NURBS,then this research sets the parameters rationally and processes parameter-oriented design.With applying Visual Basic and c + + programming,this research develops the CAM/CAD modeling system of superstructure of deep V fishing boat on the basis of SINOVATION software,and tests the usability and practicability of this system,and the finally testing results meets the requirements of the design-and-use criterion,and realizes the purpose of efficiently modeling,which confirms that this system can be applied to the modeling design of the superstructure of fishing boat.The application of this methodology and the interfaces of the system processing have been rationally simplified,which means that the modeling result can be adjusted with particular parameters.Within such methodology,the design of superstructure of fishing boat and the high-efficiency modeling can be proceeded coordinately.Such system reserves prominent usability and can be led into the processes of design and manufacture of fishing yacht.
