The Ship Propeller Design System for Coupling of CAD, CAE and CAO

This paper presents an approach for tight coupling of parametric geometry design and associated CFD and CAE analysis. It is pointed out how simulation software can be technically integrated for the purpose of an automated process chain and efficient development of flow exposed products. In particular, the established process chain focuses on systematic studies and formal optimizations for which seamless interaction between CAD,CFD and CAE is required. The software SYSWARE-Framework is utilized for demonstration of the concept and an exemplary industrial application is described in detail. Ship propeller design system is an application platform which is based on flow, simulation, optimization and knowledge driven, mainly including propeller theory design, propeller automatic modeling, propeller hydrodynamics analysis and propeller structural strength analysis. This system can validate the possibility and efficiency of the technical method of propeller integrated design and analysis, lead and promote the creation of ship integrated design platform, and eventually integrate with the overall management platform in enterprise. The research of ship production will be efficient and effective by applying the platform.
