Research on Parametric Modeling Technology of Marine Propeller
Marine propeller is a kind of typical part with free-form surface. The surface shape of propeller blade is very complex, and it is difficult to be described by general mathematical expressions, so that the modeling of propeller is very cumbersome and error-prone. To solve this problem, firstly, three-dimensional point data of propeller blade is calculated by VC/MFC programming technology and access technology of database based on projection principle of propeller blade. And then, automation and parameterization of solid modeling for propeller of different map forms are realized by programming with the interactive programming language of UG/Open Grip based on UG software. The parametric modeling system provides accurate three-dimensional model for automatic programming, dynamic simulation and numerical analysis of propeller, and improves the design efficiency of systematic propeller, and has very good practical value.
