Application of CAE in Investigating Ship Hydrodynamic Performance

The importance of CAE(Computer Aided Engineering) and its application feasibility in investigating ship hydrodynamic performance are expatiated upon.Thereafter,several finished or ongoing CAE projects developed by CSSRC(China Ship Scientific Research Center) are introduced in detail,including HDS(Hull Design System),SHIDS(Ship Hydrodynamic Integrated Design System),NTTS(Numerical Tank Test System),NTSS(Numerical Tank Simulation System) and STPD(Ship Technical Performance Database).The main functions of HDS consist of main dimension prediction,hull lines generation,hull lines fine,wave resistance optimization based on CFD and hull lines output.The main functions of SHIDS consist of hull form generation,resistance evaluation,self-propulsion factor evaluation,propeller design and propulsive performance evaluation,maneuverability prediction and seakeeping prediction.The NTTS utilizes the web and database technology to improve the model test efficiency.The NTSS can aid ship design by making full use of CFD tools.The STPD is one of the bases of HDS,SHIDS and NTSS while its data come from NTSS.The five systems are independent in the function and form an integrated system for study of ship hydrodynamic performance.
