Development of virtual test process and application effect analysis of ship resistance performance based on knowledge encapsulation
Based on the principle of"attribute subdivision and knowledge encapsulation",the application process research of virtual test of ship resistance performance based on RANS equation by encapsulating vir-tual test expert knowledge was carried out,The application process of virtual test of ship resistance perfor-mance was established and compared to the physical pool model test process.Precise prediction of resistance performance can be carried out by only inputting the geometric surface and the main scale parameters of test object,which has the characteristics of high prediction accuracy and good effect.Compared with the tradition-al CFD resistance numerical calculation,the evaluation efficiency of ship resistance performance is greatly improved,the research cycle of ship performance is shortened,and the barrier to entry is significantly low-ered.
