Abstract

Focus on the deficiency of model handling in the virtual training; it puts forward a method of the model dynamic importing. Through the establishment of virtual prototype and definition of model precision, this paper establishes the geometric model and details bases. And according to the corresponding relation between the information of the model and the precision in the post information base, it realizes the importing of the model dynamically. And the necessity and feasibility of the technology is illuminated taking tunnel boring machine (TBM) for example.
