Research of Design Method of Fan Based on Virtual Prototyping

Combinies two designs based questions: product and digital describing of design process by means of establishing suitable design process model.Based on approaching the concept,character,structure and generating process of VP and describing the character of pipe axial fan VP and VRML data conversion,expounds the method of establishing model of VP information and describing product information object model by useing of C++,provides axle virtual design example of fan.
